yeah like everyone said before me trying to play on an RTS game on PS3 is an painful experience if you have only used a PC before, even though it has keyboard and mouse support...
I would say keep you eye on "Under Siege" the RTS game being developed for motion control, it should be pretty good if they do it right.
it's the future of handheld
