@jaywhy13. You only have to look at the number of bugs that say WONTFIX fixed in XXX to see that this becomes an increasing burden on increasing number of devices. Ongoing support is the real issue.

Mark Shuttleworth has invested 10Million in getting UBUNTU up and running, I'm not clear how much of this money he has returned. But then out of the 400Million he made from selling Thaiwt its small change for him, so dont think money is not an issue in Open Source.

In any case just because Maemo 6 comes out, your Maemo 5 device is no less functional than he day you bought it. I have lots of machines at home still running XP, I dont feel compelled to use Vista or windows 7.

on the apps side of things I think Nokia's strategy around Qt is the big winner for us all and will keep the N900 running for longer than worying about the OS.
