OK, so I've got an Iliad already, but I'd still like to see something more "user-friendly" around, so I'd be willing to put down some more cash.
I limited my spendings to 300$ because I have to add 19% import VAT, international shipping and toll fees to that price to get my finaly purchase price in Germany...
6-8" screen, hardcover included!
USB port (device acts as USB harddisk in Windows/other OS)
Mobile-Phone Battery (easy to replace)
Support for HTML, TXT, RTF and perhaps PDF. Something like Mobipocket would be cool.
Suspend mode (well, every device these days can do that out of the box...apart from the Iliad, so I thought i'd better mention it...
I'm not sure about Touchscreen...it would be nice for using dictionary and for similar stuff, but I wouldn't count it in as a priority job.
OS: Linux with all sources an SDK supplied.
If a toichscreen is added, then a calender/contacts app would be cool.
Bkuetooth would be an option, but also not really among the priorities...that would just shift it in the direction of PDA's
And: A Mobileread.com logo would be pretty cool of course...
