I have mine now for about 2 hours and i did nothing but use it.

I have to say, i'm not happy.
I already had 2 or 3 reboots :/ Its sometimes very slow and sometimes it doesn't view what it is expected to view (not very clear what i mean: for example i call the menu and it stops half way through the animation)
One thing i absolutly want is listening to my music with my bluetooth headset and that works. But not always in a good way, often it skips.
Also i noticed a lot of graphics failures, like scrolling list which do not update when you scroll them.
As i wanted to use it as my primary phone i may have to send it back if it will proof it self not beeing stable.
I'm very sad because i don't see an other phone which is as good as the n900 could be and i wont buy an other phone.
Will there be firmware updates soon?
Do you have to enable the swap? Or is it enabled by default? (I didn't find an option)
I hope Maemo 5 will improve soon so that i can keep it.
