Windows Mobile and possibly Symbian and/or Android. All not very attractive OSs for Nvidia. I mean Windows Mobile is kind of the black sheep right now and will most likely remain it until the end of 2009 and WM7. Symbian is the biggest OS of all, but seems strangely outdated and is very Nokia heavy. And Android is very young and a little ugly, plus the whole Open Source thing. So not exactly the sexiest choices for Nvidia. But with Apple doing it on their own and Palm locked into TI for at least a year, nothing else out there. Well, RIM. But I have honestly no idea what Blackberrys are using and how flexible they are with their chipsets.
All in all I really hope Nvidia will support Android, because it's the most promising and it's likely gonna improve the most in the next half year (cupcake already looks very promising and is imho scheduled for late January, one more big update after that and most of the shortcomings should be history).
