The Windows Key!
I can't avoid the thing. I'm racing and next I'm looking at the desktop. How do you all deal with that key?

On my keyboard I can turn that bloody useless thing off.

Maybe you could use a software solution like AutoHotKey or similar to map the key to something else (or disable it, if it's possible).
Or use a toothpick to block it. ;)

I was pulling the key out, which is a pain with a lighted KB. The last kb, the keys were not meant to come out. i trashed it. Which makes me reluctant to try that method again. Tooth pick, eh? Off to the kitchen....
