Why is the taskbar at the bottom of the screen?

Here. Raymond explains why the taskbar defaults to the bottom of the screen (because old apps would position themselves under it a lot when it was on top). Since I defected from the Mac, I always move mine to the top and like it, but did have problems for *years* about apps moving up under there. For those few that still do, I've long since memorized the key sequence: Alt, Space, M, which flips a window into "Move Mode" and lets me use the arrows to move it down. I can understand why MS didn't want to teach everyone that and instead just put the taskbar at the bottom. : )
