Hi Chris (crylex),
I'm with you on Flash 9 and Networking (really want to access/read/transfer to from other machines) and would like to add....
A decent file manager (like DOpus

on my PC) )
Real Player so I can listen to BBC 5Live!!!
Password protected access to the whole file system (root) via the 'decent' file manager, yes I have CTRL-ALT-F3 but it's all greek to me when I get there - I'm a GUI person.
A simple 'click on the file to install' system - or is this the wonders of Linux

)
tars, bins, infos etc leave me cold.
Multi video codec player.
Thunderbird for this little machine, then I wouldn't have to separately ask for some kind of text newsgroup access tool.
Cheers
Kol
