I've always been a pixel junkie, back in the XGA (1024x768), I'd tweak my config to run at 1152x876 or so. My personal laptop is an older IBM Thinkpad R50p, 1600x1200. At work we all have 1600x1200 flat pannels, and we have three of them, but I can see using four. It does help, one for what I am doing, one for docs, one for all the junk (chat, email, etc).
