If I don't think about the price, I am happy with it

As a digital pen enthusiast, I find writing on this device satisfying. There is lag when compared to my Samsung Tab S3, but it is not bad at all. The E-ink screen is beautiful for reading documents on. If you are looking for a device to read PDF files on, annotate them, and take "side notes" then this is a great choice. If you are looking for primarily a note taking device, be prepared to buy more stylus tips because the friction of the display wears them out quickly. The friction does provide a satisfying paper-like feeling. If you are prepared to spend the money to buy the device, the stylus tip price shouldn't bother you. Also, I'd recommend getting the cover if you intend to carry the device around in a bag because it feels surprisingly fragile- as in a two year old could probably bend it in half. One last thing, don't tell your wife how much you spent on it- big mistake. UPDATE: I have been using it daily for two weeks now and no longer thing the tip wear is as big of an issue as I originally thought. While the tip does noticeably wear, the literature specifies that it should be changed when it gets to 1.5mm. I made a subtle mark on my cover at that length so that I can easily see when it needs to be changed. So far I am still on the first tip and I use it pretty heavily for annotating course readings, hand writing notes, and maintaining a weekly planner. I can't tell you how to spend your money, buy I am happy with it and if they release a third version of it, I'll buy that too.

A fantastic tool to read textbooks and datasheets

It is super light. It works better than any Kindle I ever had. It is fantastic for textbooks. I think it depends on your expectations of how happy would you be. I wanted something to read my textbooks, not a tablet. It does that pretty well. Only a minor issue is it supports PDF alone; however, I can live with this. You can convert any ebook to PDF. I use the pen to write comments on the side when I read. It does that very well. It has some latency, but it is an e-reader. Not a tablet. The battery lasts for days. Most of all, it is super light. After a month of using it, I still believe that it is an excellent tool for reading. Update: Now you can see the table of contents after the new update. I love my Sony DPT. After two months I still have nothing bad to say.

Perfect for me

It's perfect for reading papers and taking notes, without being disturbed. Writing experience is very good and sync is easy. I'm glad Sony continued this product.

This tablet is perfect for students and for anyone who uses PDFs extensively

This tablet is perfect for students and for anyone who uses PDFs extensively. I also use it as a personal notebook. This device has replaced many binders filled with paper PDFs as well as paper spiral notebooks. Some people have complained about how to felt tips go out quickly. The key is to not use too much pressure while writing on the device. I haven't used up one felt tip (pencil) yet and I have used this device nearly everyday for about 3 months now.

Don't Wait, You Will Regret Lost Productivity

This is a focused device, not a multifunction printer. Here I am comparing to my iPad Pro, which I initially purchased to read PDFs, and write notes. I thought this device was too expensive for what it does, plus its only grey scale. Turn the clock several years and I have grown tired of the weight and the eye strain from reading PDFs on the iPad Pro. Though PDF Pro on the iPad is excellent. So I bought this device and I can't say enough how much I regretted waiting. If you read lots of text and take notes -I used to take notes in meetings and quickly loose them- this is the device for you. It doesn't play movies, or emails, or internets, or games, or make you coffee in the morning. But what it performs its intended function extremely well, and is extremely light.

Transferring files is quite easy except for a bit bugginess in the software but ...

I believe this is the first Amazon review I have ever written about any item. That tells you how impressed I am with it. The most important thing I believe about this item is its lightness and simplicity for reading PDF - everything in this capacity has been designed and implemented without any redundancy. Simplicity is beauty. Transferring files is quite easy except for a bit bugginess in the software but I am sure the devs are working on an upgrade already. Overall, fantastic item for book lovers / people who have to read a lot of PDF documents such as researcher, students, people dealing with markets etc etc.

Excellent product with minor cons.

I'm a PhD student, and I need to read lots of academic articles, this is just what I want! Although there are some cons(weak mechanical strengh of the body, slow reaction time under certain files occasionally, stop functioning rarely, sensitive to EM wave like bluetooth mouse), the pros is so fantastic that I can ignore all of them. The advantages for me are excellent reading and writing experience. The battery lifetime of the reader and stylus is enough for me(I use them everyday, but not for heavy notetaking, just for reading articles and normal notetaking on the articles.). I charge them every half a week. One thing to mention, the screen doesn't sense the writing feedback by force, so remember don't put too much force when writing, or it may hurt the screen and shorten the lifetime of the tip.

Common issues that are imo not that big of a dealbreaker

I love this thing. I've used it for two weeks-ish, here are my experience with some issues I saw on reviews. 1. Battery life: I read about 2 20-page papers a day, two to three presentations in pdf form a week, and underline, highlight and scribble on them. The batteries last more than a week, which is more than what I need. You can also charge both the machine and the pen with a run-of-the-mill power pack. 2. Pen tips: I see a little bit of wear after 2 weeks, but I think one will last about a month and a half at this rate. Also seems ok. I use the ballpen type tip because I don't like the scratchy sound the pencil type tip makes, but maybe the pencil type wears out faster. Seems likely. 3. Durability: The device does look thin and fragile as one noted, like a 2-year old could bend it. But that's an unfortunate side effect of being incredibly lightweight I think. I bought the official case then decided to return, the flaps seemed cumbersome and it also looked like it would offer less protection than what I had wanted. I went and bought a "Rugged Laptop Sleeve" from Max Cases after hours of searching on amazon. I then put an adhesive pen holder on the case for the pen. The combination works great, I carry the device around in my backpack with my laptop and other hard stuff like thermos and a pencil case but no damage has been done so far. Some things I did find annoying: -EULA is icky.. -The computer software syncing the device with computer folders is slow and prone to glitches. -I don't have the best handwriting, and in terms of writing experience this is no ipad. Hence only I can read my chicken stratches now. But despite these issues and an antiquated software, this still really helped my productivity and is everything I hoped for as a grad student who had issues concentrating when reading papers on laptops, but couldn't organize all the paper stacks piling up in the house. So all in all a solid 5!

Beats the Remarkable

My use case for the DPT-RP1 is academic; research papers, company reports, etc. . I ordered both the Sony Digital Paper and the Remarkable. I returned the Remarkable. The key advantages of the Sony are: view two documents side-by-side; have a digital notepad displayed beside a PDF to record notes on (or solve a pset); no need for a wifi connection to sync documents (can be done via wifi, bluetooth, or cable); more reliable software suite; erase/highlight quickly via dedicated buttons on the pen instead of having to switch tools via a multi-step process. The Remarkable has two advantages: slightly better writing experience (Remarkable: 9/10 ; Sony: 8/10), buttons so you need not touch the screen with your hands (fingerprints).

Very useful tool

This is not a general purpose tablet. What it can do it does extremely well. I have used it to edit proofs of two books, as a sketch pad and as a legal pad. I am a research mathematician and before I received this tool I would go through several 80 page legal pads a week. Most of the material on the pads would be thrown away. Now I just delete. I also have a great tablet-- the latest Surface Pro. In principle I could do the same thing I do with the digital paper with the Surface Pro. However, the tactile feedback is not the same. Writing on the Surface Pro is very smooth on the digital paper it feels like a pencil. In fact, the tip wears like a pencil. It weighs 3/4 of a pound which is less than half as much as the Surface. Also, the screen is digital ink and so one has to have an external a light source to read it. For me this is a plus saving eye fatigue.
