i'm looking for something that can be used for watching video files on the go, listening to music, viewing and editing office documents and wifi net browsing.

i've seen that the palm lifedrive has a 4GB hdd as standard, which really appeals to me, as large SD cards are quite expensive. are there programs for palm os 5.4 that will allow me to watch DivX/Xvid-encoded files? how do i transfer data to the palm, i.e. does it function like an external harddisk or do i need to install software on my PC?

any answers appreciated!
