After updating with PR 1.2 I am very satisfy.
The mobile works faster, the battery last a little longer, Skype-video works fine. Also there is new and better OVI Maps ( well not as good as Symbian one, but hope after both are Qt related soon we will get metter one for N900).
In general for me the wait for this update was worth.

There is one thing I do not understand - almost all Maemo users are waiting for every next update, but Android users (some my friends and more) are just using their mobiles and are pretty satisfy. I know N900 is much better device in comparison to all high-end Andriods, but maybe there is different expectations from this two OS....
Or Maemo/MeeGo users are wiser. ;-)))
Regards.
