Thanks for your reply,

unfortunately Sony US refuses to sell the DPT-S1 to people outside the US, I have tried to buy from Sony US and their formal answer was that they will not sell the product outside the US. It is a pity because I think they have a great product for reading and annotating mathematical papers.

1. Is it possible to buy the DPT-S1 in retail in Tokyo?
2. Can you buy the DPT-S1 in Japan with the English menu's and if not
is it possible to modify the menu's to English on on a Japanese DPT-S1.
3. Can someone recommend a shop in Tokyo for the DPT-S1 (if (1) is possible of course.

Thanks a lot in advance

1. I highly doubt it because there just isn't a market for a foreign version of the same product.
2. Based on many sources, you cannot turn on English in the Japanese model. There is no known way to do this at the moment.
3. I've only been to Japan a few times. I recommend going to Akihabara, that's where all the geeks go to buy their electronics, Akihabara is famous for that. The selection there is just ridiculous. I'm certain you can find the DPT-S1 there.

is there a case for this unit? thx

I just figured someone could be interested in the script I had lying around my computer for quite some time now. I use it to crop PDFs for the reader. Example invocation

:/croppdf -o outfile.pdf infile.pdf 10 20. 500. 700 20 30. 500. 700

If you just run it without arguments, it gives a command summary for all features. Runs on Linux/Bash with ghostscript (command gs) installed.

Or you can buy it through your friends in the US. One friend of mine bought it through a transferring company

Looking only at the self-promoting video at the Sony website, I'm a bit worried about the contrast of the display. The background is quite grey...
https://store.sony.com/gsi/webstore/...2FHVavA8FOFTe2

The video would like you to think it's better than paper for lots of think but what strikes me in this vid is that I can't read so well than on the paper due to this apparently low contrast...
I had the same problem with my PocketBook Pro 903.

[ManDay]

It's kinda like unbleached newspaper print. Not particularly shining but nothing to worry about, either, imo.

[j.p.s]

Is the web browser on the DPT-S1 able to acess local files via file:///path/to/local/file.html URL method?

Hi all,
I am starting to really enjoy my new DPT-S1.

I'd love to take it on the road with me (think packed carry-on bag for airplane rides and what not).

The device is beautiful but it feels delicate. The sleeve that comes with the device is nice and elegant but it does not seem to provide much protection when placed in a packed bag - in particular I am afraid the (tall) device will bend in a packed backpack...

Has anyone found a hard shell case that fits the DPT-S1?

Deosnt have to be a perfect fit. Even something as old fashioned as a tin box the device the device can be placed inside with a bit of padding, for travel protection, will be fine.

Any and all advice/experiences welcome.
Many thanks!

as far as i know, there is no case made for the DPT-S1 at all, from anyone. if you find a suitably sized tin with room enough for padding, i guess you can use that. i ended up purchasing a folio made for a note pad, took the paper pad out, and slipped in the reader. i purchase this from office depot: FORAY Pad & Tablet Folio, 9 1/2" x 12 1/4", Black (# 844148).

Thank you, rem736! I did see mention of this item earlier in the thread. Alas, Office Depot currently says "Out of stock for delivery". No luck at the local Office Depot either.

Amazon has some options (if you search DPT-S1) but they all seem not much hardier than the original we get from Sony.

you should be able to find it almost anywhere. it shouldn't be limited to office depot. on amazon, search for "FORAY Pad & Tablet Folio, 9 1/2" x 12 1/4", Black (# 844148)"

Good point. Ended up buying at Office Depot (thanks to you):
FORAY® Leather Padfolio, Zipper Closure, Black
Item # 173150 OfficeMax # 25003629

Slightly more expensive, had more junk for me to take out (inc a calculator but the thing "swallows" the DPT-S1 while still in its Sony sleeve. So I'm happy. Thanks again!

[md02439]

@gbgbgb, @rem736: could you make a photo of the DPT-S1 in the Padfolio?

Thanks

[rem736]

@md02439, here you go. this folio has an elastic strap that wraps around to keep the folio closed. it is sized too perfectly for the DPT-S1, leaving the pen sticking out of the cover, which is a negative. it does have a pen holster on the inside spine. however, using it will cause the reader to stick out. so i decided not to use that holster. besides, removing the holster from the DPT-S1 leaves a hole, which could lead to dust entering the unit.
