>>For sure - but Windows is not the goliath dominating all of IT any more.

Hmmm
That might be true of gov't installations, but:

Just about every ATM in the US now uses windows.
Every hotel in the US uses windows for reservations.
Every POS station in the US now uses windows.
Unfortunately, I spent some time in several US hospitals recently and every nurse and every MD is now working at a windows W/S.

Go to Staples, or any similar store and try to buy a laptop that does not have Windows installed.

I might not be a goliath, but it's all over the place.
