I just wanted to defend Android responsivnes a little bit. I use HTC Desire as my primary phone and don't have any problems with speed. Last time I played with an iPad I didn't notice it being substantially more responsive. Maybe when you use iPxx you get spoiled and notice some lag on the Android devices. In general for XCsoar it doesn't matter that much. I'm sure Android can be quick and battery effective enough even for a complex application like XCsoar.
It might not be an easy task, and the code base might have to divert.... I'm quite curious how much. XCsoar is very remarkable to support WinMo, Win32, Android and maybe even desktop Linux from the same codebase. What matters the most for XCS is the variety of Android manufacturers and form factors . That is great. And we're all really lucky that Max is working on a stable port. Thanks a lot.
