I think you also need to take account of those of us who have a foot in each camp. Most of the time, I want a device to work, quickly, easily and out of the box. But, I also want to be able to challenge it (and myself) now and again by pushing those boundaries. Preferably, without trashing its general usability in the process. Which is why something like Maemo is perfect for me (and maemo 6 might be even more so).
Of course there are other factors. I neither said nor implied short time was the only one.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
