I think that thanks to the software and also a good hardware layout the PocketBook 360° is the most versatile device.
It features goodies like on-screen keyboard, note taking, even calculator and game of chess. PocketBook firmware is traditionally very, very good, as you can see in previous models (301)
It does hyphenation of text. The review specifically says that there is very uniform "typographical grey" on fully justified page. This is something other readers lack very much.
For some formats, like FB2 or TXT you can set LOTS of options, like font type, justification, margin width, (possibly line distance).
For PDF format the device does reflow.
The review also tells us the device uses Epson controller.
The price seems to be substantially higher, but this is European price. If you import Astak device to Europe, you have to add about 20% VAT plus transport cost plus very traditional "Everybody screws Europeans, so why shouldn't we?" "negative rebate". As a result, you usually get 1Eur = 1USD price.
