Not to start a flame war, but people who move their taskbar to the left edge of the screen are extremely sinister and should not be trusted, because they probably use tabs instead of spaces, and vi instead of emacs. Putting your taskbar on the right edge is fine though, as is using spaces and emacs. Putting the taskbar on the top or bottom just means you're gay, not that there's anything wrong with that. ;)

Tabs on the other hand (and of the other type) should be able to move freely between all edges of all windows.
