You all know what average users expect:

1. Atleast lite (or demo) of Papyrus (with .doc support)
2. Browser (this one is tough), maybe Senex's idea is good ? Wasn't new Voyager layout engine written with css in mind ? Ofcourse TCP/IP needs to be there.
3. Good music player (ANR)
4. MPlayer
5. Simple, but effective filemanager
6. SDK

Few table games, ftp client/server and other misc apps won't hurt.
I think that bootable cd on x86 with pearpc and on mac won't hurt.
