Quality control: I don't care how much you clean up the interface if the packages flakey UI: Why can't I just upgrade all packages that are available?
Right now maemo.org has how many packages that you would consider beta? 15-30 I would say. Noobs should be prevented, by default, from installing packages that have not been through QC.
Right now maps, FBreader, and OpenSSH will not upgrade through App Manager ( that's 40% of the 3rd party apps I have installed on this unit ).
