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.

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.

I have owned this e-reader for a few weeks now. Bar far the best e-reader for reading page size documents by far. Purpose of this devices is for reading large amount of text. If you are trying to find something specific in the text then use a computer and search for it. I have to read 100's of pages at my work and this makes not needed a printer a huge benefit! Do not manage/organize files natively on this device as this can be done far faster and easier on a computer. I transfer several documents to this device, read through them and mark them up, then transfer them back to the computer for later retrieval as needed.
1. Zoom sometimes activates inadvertently. This doesn't happen much but the few times it has happened made me wish I could turn this feature off.
2. Lag time. I know this is not a computer, but the lag while writing is a little annoying. It is barely perceptible but I am a fast writer so sometimes I have to wait a second for it to catch up with me.
3. Bad case. The case the e-reader comes with is flimsy and doesn't offer any real protection. I am looking for something a but tougher to protect the device.
Pros (far outweigh the Cons):
1. Read pages at their original size without zooming!!!
2. User interface is mostly intuitive.
3. Transferring files via USB is very fast!
4. All notes are readable in standard PDF viewing software - nothing is proprietary!! (huge bonus for me as most e-readers don't do this).

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!

Perfect for academics: carry all your papers with you, books too, annotate, use it as a notepad, etcetera.
