I'd like to see a firefox browser on os10. As well as Skype. My guess is that 3rd party developers saw RIM, running OS5, launching OS7, at the same time planning for OS10. RIM must get OS10 running and stick to it, but there are many 5 and 7's out there for awhile. Os7 was stupid to go to, better to have kept 5 until os10.
