I thought the ipod touch had wifi? is this not the case? (wondering why you wouldn't be able to connect to your work's network). Also, you don't have to have iTunes to synch your ipod. I use winamp for synching my 4g ipod to my PC. winamp also lets you sync "both ways" which iTunes does not.

Also, apple just released a dev kit for the iphone/touch, so you'll see a lot of 3rd party apps for them really soon.
