I think many people's problems is that Nokia are very, very bad at communicating with their customers (e.g. until recently the "uncertainty" with "PR1.2").

Maemo is not really open source (e.g. a few closed components).

Also it appears that the n900 will not get the "free" version of OVI maps. It's really frustrating watching the Nokia adverts on the t.v. knowing all Nokia customers can get OVI maps except you.

At least with MeeGo on the n900 I have a chance to own an open source device (in the true sense of the word).

When Nokia abandon the n900 then at least MeeGo will still be developed within the community.

QT will really help too. I can write a python-based QT app and run it on my LInux desktop, MS Windows and my n900 running maemo - without modification.
