I have a Q7 as well. If I'm honest, it doesn't see too much use.. its just not *quite* there. Really do think of it as a poor mans NIT with a bigger screen (but no higher resolution). It is a bit sluggish, to the point I've not tried open office or evolution on it (Abiword takes around 12 seconds to start up. Thats not terrible, but I am very impatient!).

With regards to Mer, it does work but I wouldn't call it day-to-day usable. It does very much feel like a work in progress, but because the latest work in Mer is going with a different GUI (which demands hardware capabilities beyond that of the Q7's) progress is slow. Also, if you run out of battery Mer will not shut down nicely and there are some horror stories surrounding that.

On the plus side, there is an excellent and very functional android build for it called QDroid. Its a touch rough around the edges but really quite usable once you get it set up.

I'm told WinCe runs pretty well, but i haven't got round to installing it.

A few good plus points- form factor wise the large screen is very nice (would have liked a better resolution). Battery life is excellent. And it is suprisingly pocketable.. fits in my back trouser (combats) pockets fine, easily in a coat pocket.

Main gripes- slow, dont like the plasticy feel, and I need a keyboard!

For the record, I've read reports that the V7 does have improved performance... to be honest, I would imagine it would have to because the Q7 doesn't feel like it could push out to a HDMI port...
