I have to say, mine has slowed down, crashed, had problems like any other device that actually multi-tasks. But I have had to pull the battery maybe once or twice, very rare if I was testing some new software in extra devel that I had not tried before. Nothing I use regularly has caused it. Supertux I am not surprised, as when I tried to play that (granted months back so it might have improved) it seemed like a very rough recompile for the N900 without any tweaking specifically for the N900 at all (the controls seemed awkward).

As someone else said, its a MASSIVE upgrade over Windows Mobile. I found that, with an OFFICIAL firmware, explorer would just crash immediately upon bootup for no good reason. Windows Phone 7 should finally fix that, but then that is a completely different beast entirely to Windows Mobile and unlikely to be as flexible, hence why its called Phone not Mobile, its an actual Phone OS this time not a computer.

Why is it not as stable as iPhone? You gotta be kidding me. There is only just talk of iPhone doing multi-tasking as most likely it will still have strict limits on what can run at the same time, how MUCH can run at the same time. THAT'S why the iPhone is more stable, if you are running a game on iPhone that is pretty much all you are running and at a vastly lower resolution than the N900. Yet, Angry Birds runs excellent on the N900 at that much improved resolution.

I just wish Nokia would pull their finger out on OVI Store so I can buy the level pack but presumably something is going on due to the Meego change, possibly demands of everything on OVI to be Meego compatible before it goes mainstream. I wouldn't be surprised if Maemo 5 even switched to RPM some time this year for compatibility.
