Its not a nice screen and supports TXT, RTF and HTML books out the box, with software available for PDF, LIT and CHM. The only minor annoyance is the supplied word processor, pocketword, runs very slowly when a large file is being edited. As long as you dont alter the large file, its fine. There are no good free alternatives. Plays music too, and TV control. Of course, its a MS operating system. You cant directly connect it to any non-windows system. Not good. But if you get a USB securedigital drive, problem solved easily. You might occasionally need a windows box because of the stupid install programs, which expect to see an installed copy of activesync before they extract the cab file you need to actually install the software via SD card. Once youve done that once, you have the CAB file you need for reinstallation. You can put linux on this, but obviously its not an official program and I havn't tested it.
