One of the problems with ultra high resolution screens is that they often display text in ultra low sizes. My little Toshiba tablet is a case in point. It has a lovely display with loads of dots that I can't read. If you have a similar problem you might be interested in a Windows 7 feature that is rather nice. In the screen resolution dialogue box there is an option to "Make text and other items larger or smaller". If you select this you can enlarge most of the hard to read things on the screen by 125 and 150 percent.
It doesn't work for everything, programs that insist on rendering their own dialog boxes for no good reason (step forward Adobe Photoshop Elements) will still be hard to read, but it beats the alternative, which was to set the resolution to a value that didn't really fit the display and then have everything slightly blurry.
