Well I've got my 2690wuxi up and running and I have to say it is pretty impressive. It is a bitter sweet moment, since I have $1650 less than I did when my LaCie started dying, but now I've got the latest greatest. I don't really have a lot to say except that it looks great.
It definitely has a different "feel" to it from my old CRT and I need to get used to that, but so far so good. One thing I've noticed is just how much software is designed for wide format screens these days. I had the traditional proportions on my old CRT and it is amazing how much better Aperture and Bridge work in a wider format.
I don't have a ton to say about it except that is seems to deliver what it promises, but if you have any specific questions, I'd be glad to answer them.
