The epod does not have a hardware keyboard; the on-screen keyboard works fine, but it can cover up important areas of the screen (especially in double-size mode) and has to be moved occasionally.
I have used the double-sized on-screen keyboard to touch type with both hands, and while a bit small, is pretty easy to use.
For short messages, the on-screen keyboard or Calligrapher handwriting recognition is fine. For longer messages or data entry, your best bet is to attach a cheap USB keyboard. That is how I am composing this message.
