The guys over at LifeHacker.com have noticed that Windows Vista looks a lot like Mac OS X. That doesn’t really come as much of a surprise, the way that software (in the larger, general sense) evolves; vendors see what works for other companies, “borrow” or “steal” (depending on your point of view) from each other and build on it. The devil, as they say, is in the details. I’m sure there will be plenty of “yea, but” posts pointing out differences and places where Microsoft improved upon Apple’s work (or failed to).
OS life is going to get interesting again, for a short while.
