If there wasn't reason enough already to get a nice big new monitor, now i have an argument that might convince me to actually do it: the Desktop Sidebar.
This little puppy can do soooo much. It's been said "You don't have to wait for Longhorn to use sidebar. Try Desktop Sidebar!" So for all of you geeks out there who aren't geeky enough to be using only linux, check it out!
Check out the
Desktop Sidebar homepage!
Take a look at some screenshots:


It has 16 different colour schemes, so you can make it blend in with your desktop theme. It's hany, and although it takes a little getting used to, i find that I'm enjoying having it around. If I ever find that I need my full screen, I can set it to auto hide. Now, at a glance, I can see who's online, check the temperature and forecast, monitor my computer's performance, check the latest headlines, control winamp, and type in a command or select a quick launch button. It's customizable and very pretty :)
