My current desktop.
I love the slide show feature of Windows 7 since I have a folder of 385 pictures I cycle through. And yes those are 4 different web browsers in my taskbar, I like having the ability to use whichever is most appropriate when I need it.
Also on this computer I have ubuntu 11.10 and BackTrack5. It's kind of funny, ubuntu displays the clock and logout button twice, but the picture spans the monitors nicely, in windows 7 the taskbar is only displayed once, but the pictures don't span very well. BackTrack just does not play well with dual monitors, will only duplicate my display.
EDIT: Added ubuntu and BT desktops.
