On another topic, a word of caution about high-resolution laptops. I recently bought a laptop to replace my old one that died. It was hyped up to have super high-res graphics. The problem is that it will make all web pages look microscopic. Squeezing so many pixels onto a laptop screen means they have to be smaller, which scales down the size of everything proportionately. Even though there are settings you can fiddle with like text size, and display resolution and even a zoom page control in internet explorer, these all produce poor or blurred results. There is really no eitzah, other than getting a humongously-large sized laptop or monitor, if you like such high resolution.
Otherwise, I have found that with my older 13 inch machine which was XGA (1024×768) I was happy. For a 15 inch which I just bought now after exchanging, 1280×800 seems about as high as I would go, or for a 17″ , which was my previous machine, 1440×900 was about right. Going to higher-res than that will probably leave you disappointed and squinting and moving uncomfortable close to the screen to be able to see.
