I develop for iOS and Android using LiveCode ( http://runrev.com ), it is a modern cross-platform HyperCard descendant. It is really powerful and fun to use, not to mention that it can deploy native applications to Mac OS X, iOS, Android, Windows and Linux. Personally I use a MacBook as my main development machine but at home I sometimes use my Fedora 15 desktop. I have LiveCode running in both of them and I deploy to to all systems. Curious people in here might want to check it out.
