Markus, You'd be surprised by how much stuff people have running on their phones. 2.0/2.1 seem to be better at handling it with a game but in general, I think it's an issue of educating people to shut off sync and certain wasteful tasks while playing games. I REALLY wish Android would add a game-mode as a core feature of the OS, which suspends all but essential functionality (maybe user selectable, such as take phone calls, get SMS and optional email, other services, etc). Then a game declares itself as such in the manifest and the OS knows to give it better priority and stop other things from lagging it out.
I find that when I shut off sync and kill most everything running, my games run smooth, but even on my nexus one if I fail to do all of that, I get lag.
