Thanks man, the more info the merrier, I'll get reading.
I've just finished a game for Windows, just trying to see if I can get it released now. But after looking around, I really think it's best to do simple games for as many platforms as possible. So I want to get started on this whole tablet/phone stuff and see where it leads me. For one thing, I need to start working with touch-screen instead of mouse, so my whole thinking about games needs to alter slightly. I'll look for the cheapest possible phone/tablet and try to think up game ideas that work on that. Then I can look into other platforms.
As you said in an earlier post, Windows 8 looks most promising right now since it's under-saturated. I'm going to install W8 on this PC, then maybe get some touch-screen device to develop simpler W8 games for tablets or whatever. So I guess right the best bet might be some cheap W8 tablet or... something, lol xD
