1. Something akin to ListPro for PPC (http://www.iliumsoft.com/site/lp/listpro.php)
2. Perl
3. TV Guide applications (Loading web pages for this takes some time)
4. Calendar/ToDo/Contacts with sync capability (I believe this is being worked on for the GPE suite)
5. Larger board size for Four Rivers (i.e. tougher play )
6. Auto play in AisleRiot (really hate having to tap every card to put them up when it's obvious that it's a winner)

I have to say, though, that overall I'm very impressed with this machine, even with the level of functionality in the alpha/beta applications.
