I was going to buy the N800 for listening to internet radio, web searching, emailing from remote/ coffee shop locations. Showing h264 clips from my portfolio to clients and of-course " youtube ".
All the above can be done on the itouch, and with ease. Youtube plays the way it should unlike the N800. The itouch is cheaper; and stupid as it sounds, more sexy looking. If I need 16gb then 100 bucks is a no brainer too. Anyhow, just IMHO.........
