I also suggest, have a look at

have a look at video demo at

You can create your own program - or compile existing one with different options.
There is :GASP: terminal emulator that runs [bussybox version of] Bourne Shell. Yes. You can run included busybox Linux binaries from the terminal emulator.
Have a look at
http://pocketbook-free.sourceforge.net/en/index.shtml for user contributed programs.
You can even try software, if you install SDK (software development kit
that includes device emulator!)
The entire device was tailored exactly to the demands of users at
http://www.the-ebook.org . Using translate.google.com you can browse the forums and see discussion. Hardware was also tailor made. Look at the cover/lid.
Last but not least, have a look at youtube and search for pocketbook 360.
