It would have been nice to be able to check more than one item, since I do many of those items.
My primary purpose for my Z (SL-6000) is notes. I keep a journal of my activities (Sys Admin, work, life in general). I use Zeditor for this.
I also listen to Oggs, and the occational MP3, as well as serve web pages when my Z is at home (and connected to my home wireless network).
I also use it to read web-zines off line, which I yank down with wget, and later read with Opera.
