I make much use of ctrl-arrows to new virtual desktops on my MacBook to get more real estate, organize like-applications and windows, and help focus on a task at a time. I was surprised not to find some feature built into Windows 7. Am I wrong? If not, what program do most use for virtual desktops in Windows?
Keyboard shortcuts to slide to a new desktop
Sliding a window/app to an edge activates/moves the app to that virtual desktop
Zoom-out view allows you to see position and location of all windows on all desktops
Taskbar icon/view allows for easy two-click jump to any desktop
Remembers which apps open in which virtual desktop, on re-launch moves you to that desktop for app launch
(If you know any additional useful/cool features to hope for, add them as comments and I'll edit & add here.)
[And, no, 'install Mac OS X' is not what I'm looking for.]
