I've got two mice.

I know we constantly get the question about using two mice. I actually think it's a pretty bad idea; even if the OS could somehow use them, it'd be hard to aim with both hands.

Anyway, I was using Parallels on my macbook to play an old video game. The windows drivers for my mouse can do things the mac drivers can't, so I plugged the USB device "directly into the virtual machine".

The neat thing is, when OSX isn't focusing on the Parallels window, the windows mouse still works inside windows. I can keep playing in windows even though the mac mouse has its own touchpad and pointer. The Mac screensaver will even kick in, because Mac doesn't see the windows mouse at all.

Anyway, if somebody still wanted 2 mice, they could run a VM on one screen with the natice OS on the other. They could plug one mouse into the OS and one into the VM, with 4 tables on one and 4 tables on the other.

There's no reason you can't run windows inside of windows.
