It's okay, but doesn't have many useful featuress apart from browsing files and being able to launch most fxe.
I think there may be a text file viewer, and there's an address book thing you can download for it.
What would be really useful is if you could view picture files such as .jpg or .gif etc.
and maybe play mp3/mod/mid files, or even divx as it is a nice environment for doing such things ... more so than free launcher anyhow.
i saw a PDA running linux, that was pretty sweet ... especially the back light! but not really interested in running business apps
