It arrived today.
I seem to like the resolution set to 1600x1000 but it goes up to 1920x1200.
It has so much space that I don't even really need the 17" screen on my laptop but it is still nice having two displays.
I've got my mouse on top of a book so that I can use it with my hand in a splint and my new kitten Katrina seems to really enjoy the towel that I have also had to put down due to the splint on my hand.
