King of all updates for N900 would hold the folowing: - Portrait mode accross the UI. (I know it prbably wont happen before Maemo6) - Flash 10.1 (Sould be 2010 Q1 so might even happen) - Ovi maps free navigation (as mentioned earlier, Nokia has said every phone with GPS will have this from marh onwards, so in principle it should include N900 hence it will be sold also after march.) - Some useful Java runtime (probably wont happen ever at least by official Nokia implementation, but it would be very welcome. I have heard of some NWR Nokia Web Runtime or someting like that coming to Maemo5 & 6 but not quite sure of what is it capable of) - SyncML or some other built-in solution for perfect syncing with Google mail, contacts & calendar. (also won't probably happen by Nokia, but thereare some promising community projects going on that probably will solve this in some point) - many others ofcourse but this was from the top of my head...
