Can support up to 1.5 GB in add on cards (1 GB Compact Flash and 512 MB SD card). Can use a Compact Flash wireless card for internet (Opera) and e-mail. Some people have even set up small web servers. Can play MP3s, and if you turn off the display, it'll last for hours. Built in keyboard. Hancom Office for reading MS Office files. I haven't been able to get Sambafs set up yet, but there is a version out there for it. It's been fully drained once, but was back to normal after a charge and boot-up

Downsides: battery life is short when using wireless card, keyboard is not for people with large fingers. Doesn't have all the software the Palm based palms have (but being Linux, some open source programs could be reworked/compiled). Fairly thick.
