Honestly, it took about ten seconds to learn it was on the other side. Is it really that much trouble for people to adapt? It's been less than a day and I don't even notice it's on the other side any more.<p>Yes, there's the argument that people should (and can) put it wherever they like, but seriously, within ten or so instances it's relearned.
Or get yourself a mouse with extra buttons (I bought a Logitech over 5 years ago), and map those buttons to minimize/restore. Or even better, use a stack that remembers which windows you've minimized, and quickly restore them in the reverse order.
If you're worried about what side of the window your close button is on, you're doing it wrong. Learn the keyboard shortcuts and move on to more important issues.
