Thanks, Bork. I've got a Dell DELL U2515H , which is 25" monitor, with 2560x1440 resolution. I think I paid about EUR320 for it, so it was more expensive than your find. It has thin bezels, which really grow on you, and tons of ports on the back, most neatly hidden behind a removable panel.
I think the one you have is 2560x1080. I'm hooked on the 1440 vertical resolution, though, and my neighbor has a curved widescreen. So now I need three-thousand-something by 1440!
By the way, I've installed
AquaSnap for window management, and it is pretty good.
Divvy also looks promising. What is nice about AquaSnap is that it actually works
inside of Visio, for tiling/snapping ShapeSheet windows into quadrants, for example. Very cool.
