I like the comments from the person who has 3 eBook readers: JetBook, Kindle 1, and Sony PRS-505:
I own a JetBook (~$200 at Fry’s as well), Kindle 1, and had a Sony PRS-505, so here is a review.
Overall it is a great lightweight replacement for a pocket novel/book, esp. if you have ebooks already. It is the one I carry with me every day.
It is not for impulse buyer (no wireless) or someone who needs technical documents. For this look to the iRex or Kindle DX for an 8″+ screen.
Good:
Smaller than Kindle, pocket sized and light.
Instant page turns
USB charge (like Kindle 2)
Multilingual support
built in dictionary is not bad, but not equal to Wikipedia.
Screen is LCD and IMO as good as the Kindle 1 or Sony PRS505
SD expandable (Get a Class 6 SD card or your system will slow down)
Built in file management
Half the price of Kindle or Sony
Fair:
PDF support is OK, but currently no reflow of text.
FYI: Reflow is supposed to be available in a firmware update. However, with a 5″ screen, technical diagrams and large pictures are too small to view. IMO neither the Kindle nor the Sony viewed these documents well either.
Battery life is not as good, about a week of moderate reading between charges, maybe 12-16 hours of constant reading.
Was a little slick and hard to hold, but either a silicone case (ebay) or a camera wrist strap fixed that.
Bad:
No store (like Sony) or Whispernet, you must find ebooks via other stores. Although with Amazon & Sony’s DRM issues, this might not be all bad.
My jetBook has Battery life - 20-22 hours but other part of this review sounds correct for me.
