This thing is awesome. Incredibly light, handwriting is really cool, page turn speed is good. However, it’s far from perfect. I’ve been playing with the device for the better part of a day with the most current firmware at time of writing.
- Uh, the glorious 13”+ E-Ink screen maybe? Touch works quite well.
- Handwriting is fast. Not blazing fast, but coming from a PRS-T1 it’s pretty speedy. As others have mentioned elsewhere, the lines appear first fairly jagged, then get aliased to screen resolution a few seconds after you stop writing. I’ve used the device to take notes in a meeting now and it did a good job.
- Organization of documents is pretty nice. Being able to create folders is excellent.
- Resolution is fine for my taste. Pixels are visible to my eyes out to about 40-50cm. Could be better, no biggie.
- HTML5 speed tests say the WiFi runs at about ~2.5Mbps. Might be faster for http-based downloads, but the standard “download an ISO” test fails with a “Content is not supported on this device” error. Considering it takes a few seconds to render even simple pages, this should not be a primary concern.
- Pen holster is sorta wifty. Seems like the connector will not be very effective after a few dozen connect / disconnect cycles. I’m worried about losing my pen on the street if I carry it outside my pack.
THE BAD (remember this is v1 of the product line);
- Search is **really slow**. A query for "david baker" in my copy of “Lehninger Principles of Biochemistry, 6th Edition” takes > 30 minutes. Obviously not usable in any sense of the word. (OS X says the PDF is 37.4 MB in size).
- Handwriting is a little wonky. It doesn't automatically detect pen orientation, so if you change that while you're writing your writing drifts away from the tip of the pen
- You have to dig through the settings menu to change note templates (ie; standard lined paper, grid, etc.) This should be something you can change when you create the note.
- Obviously no support for formats besides PDF (this makes sense- annotations and stuff on lots of ebook formats would be non-trivial or impossible.) But it would be cool to have perhaps a “reader” app that just reads and has a subset of the annotation support for PDF.
- Honestly, construction of the reader seems a little shoddy. The PCB and usb connector casing are visible through a fairly large (~1.5mm) gap at the bottom of the unit. Not a big deal, but it’s not real confidence inspiring.

It annotates documents well, but does a terrible job managing them and the software is unstable. Specifically, although you cannot use dropbox you can use box, but if you delete or move a file on your computer it will not do the same on the device. Even worse, when the Digital paper syncs again it re-adds the deleted or moved file back on the server resulting in duplicate and eventually triplicate and more copies. Also, if you edit a file on your computer too close to when you edited it on the digital paper the syncing is not very sophisticated and will sometimes replace the new file with the older one, resulting in lost annotations. Although I was ready to deal with some of these compromises, the last straw was when I turned it on and all of my documents were gone! Instead I received an error that the memory needed to be reformatted. I was able to restart and recover everything, but this is unacceptable. I returned it to Sony within one week of receiving it and even that was an ordeal as the off-shore representative actually suggested that it was more than fourteen days - even though it had been about seven.

This is pretty good for the first version of a product. It comes with all the advantages and disadvantages of e-ink that one would already expect. It works great for smaller (page number/file size) letter size/ A4 size PDF documents but it's processor is underpowered for bigger documents. Search on bigger documents is pretty much unusable.
It only works with PDF documents which limits the usage scenarios.
Making notes with the pen works great.
I was not able to set it up to connect to a network. They made that too complicated. You will probably need a fully staffed IT department to get that working.
Still, its a promising device and I hope the next version adds ePub support, a much faster processor and memory so it can handle search and larger files like blueprints better.

Rated 4 out of 5 by Erzatx A unique product
The DPT-S1 is fantastic for reading and carrying around thousands of PDF files. The note feature works quite well, except that sometimes adjusting the pressure on the pen can be tricky. The screen is really large for such a light device. The only issue with the pen is that it is smaller than a regular pen, and it is not comfortable to hold for long periods of time if you have large hands.
Now, I have so far been unable to connect to my company's WIFI network and sync the library with my PDF on Box.com. Having to rely on USB for syncing the PDFs is a big hassle, and I wish the network connectivity was better on this device. The device can handle simple WIFI networks such as a home network, but not connect to secure corporate networks with two-step authentication and other security features.
I recommend the device only for people who read and annotate a lot of PDFs, otherwise it is not quite that useful for the price. Hopefully the next version of the software will fix some of the kinks with network connectivity and file syncing.

Don't think of this as a replacement for your laptop or as an alternative to a tablet. It's a replacement for the piles of reading you need to lug home or on the train to stay caught up.
First the good: The DPTS1 is feather-light. The screen is sharp and big -- a full-size page so there's no scrolling around to read a document. Reading in bright sunlight is a pleasure.The pen works (no batteries!) for annotations and highlighting. And the ability to sync with a network folder makes it simple to add or delete files.
Now the bad: The pen isn't so great for taking notes in meetings or court. When writing, the screen sometimes treats the pressure from your hand as a command to flip the pages forward. And the handwriting is too imprecise for extensive pages of notes. The pen works best for highlighting and notes in the margins.
Finally, the price is sky high. If this reader were $400, it would be a no-brainer, and I would buy one for everyone in our law firm. The price will put it out of reach for many would-be buyers, and that's too bad.
Overall, if you do a lot of reading for a living, this is a great choice to lighten your briefcase and save your eyesight.

Rated 4 out of 5 by Cellist Superb, but with ONE glitch
ULTRA large, far beyond any tablet I know of!
ULTRA long battery life
Easy to use, clear display
SLOW page turns... sometimes very slow (multiple seconds). I wanted to use this to digitize my immense sheet music collection, to be able to rehearse various pieces (I play cello) without lugging 20 pounds (no exaggeration!) of sheet music and scores around. But the pages will not turn fast enough to perform from. To teach from, rehearse from, yes -- to perform from, no. If slow page turns are no problem for you, this thing is darn near PERFECT!

About me: Software developer who uses lots of notes to organize and structure ideas, designs, and implementations. Notes often include diagrams. I am also a Kindle DX owner and prefer e-ink technology over backlit screens for reading. Page turning is not as fast on e-ink and color is replaced with grayscale. If you cannot accept that reality, this is not for you. I don't find either an issue and the ability to view multi-page displays or scroll through pages by holding my finger down at the end of a stroke more than compensates for the "slowness" of page turns. Slow is relative, it's really "noticeable" vs instantaneous.
Using touch and gestures for selection and navigation.
Writing is very near to natural writing on paper. I replaced the nib in the pen with a felt nib from a Wacom pen and it performs even better.
I have been able to replace piles of paper notes with well structured notes that stay together.
Unlike a paper tablet, I can insert pages or add pages to keep notes on a specific subject together. This alone is worth the hefty price for me.
Organizing notes in folders to keep context around information is essential and the DPTS1 does this fairly well.
Workspaces allow me to link together documents from different folders into a common access point.
Size is perfect providing a full letter size page.
Very thin and light weight.
Menus are intelligently placed and structured and stay out of the way when not needed.
The gestures can be a bit finicky, especially the zoom in and out. I find moving a little slower helps.
The buttons placed at the bottom of the tablet cause problems when writing towards the bottom of the page. Too much pressure from my wrist can suddenly change to the home screen or display the menu. These would be much better placed along the top to stay out of the way of writing or holding the tablet.
Likewise for the power adapter plug and power button. They would be more convenient at the top when writing while plugged in, especially writing off-table using lap or holding the tablet..
It would be nice to be able to set the thickness of the pen rather than have just fine and bold. Or at least have some variation within each of them. Fine is a bit too thin for my taste, bold is about right, but then I have no way to bold specific text if everything is in bold.
Add copy and paste functionality. e.g. add a marquee tool that allows me to select a section of text or drawing and cut or copy and paste to another area or to another document.
Add a Windows Explorer-like view that allows me to move documents from one folder to another on the tablet. While doing this via the computer works well there are plenty of times it would useful on the device.
Add black text color. Current options are blue and red.
Add two or three highlight colors. These could be displayed as varied shades of gray and identified by color in the menu.
Include more pen and nib options.
Add a notebook type cover that can fold around back to support the tablet while taking notes off a table.
Most of all keep it a single-purpose device. I don't want to play games, or surf the web, or take pictures, I want a efficient and effective tool for taking and managing notes. This device does that extremely well and with a few minor form changes could be near perfect.

Rated 2 out of 5 by MattZN Hardware ok, software incomplete
It works but there are some significant deficiencies that make it considerably less useful than it could be otherwise.
(1) Pen sensitivity is only good if you move the pen slowly. Handwriting at normal speed results in very clunky output. The tablet misses pen motion when the pen is moved quickly. This makes it difficult to use the tablet as a paper replacement... real paper and pen winds up being superior.
(2) Network sync is extremely primitive. It's impossible to access a large library of PDFs in any convenient fashion because the tablet wants to download it all. A samba/windows share accessed like a live filesystem with download option would be far better.
(3) There are many PDFs that I want to mark up which the tablet will not allow me to edit due to a read-only bit in the PDF, forcing me to run the PDF through an adjustment program. This makes no sense whatsoever. The tablet should allow me to mark up any PDF.
(4) I didn't expect a fast reaction time for a paperwhite display. However, the UI elements for moving between pages and editing are unfortunately very primitive, making working with a large document difficult.
All of these problems could be fixed. Honestly, I don't even know why Sony produced the product with the software in such a decrepit state. It could be so much more, with a little effort. I'm giving it 2 stars because basic functionality works, but it doesn't work well enough for us to really use.
