Good news everyone! My STAReBOOK arrived just now. I can't give you a big review yet of course, but I'll just put up a few pictures of this pretty little device. A few things I can say so far:
Booting up is about 4x faster than the iRex iLiad. The device is very small and light, it's easy to hold with two fingers (!!!) and it comes with a nice set of accessories. There is even a 512MB SD card in the box.
It also has a user replaceable battery (!!!) (as you can see in the pics) and it's recognized as a mass-storage device in Windows, showing up as two devices, one for the main storage and one for the SD card.
The device has some of the style of an Apple iPod and feels nice in the hand because the back is slightly rubberized. I have not transferred any books onto it yet, but I'll do that this afternoon and try my best to give you a short pre-review this evening (German time).
For now, enjoy the pictures! (sorry for the bad quality in some, I was in a hurry...)
