Probably somewhere more efficient but with less useless (but admittedly cool looking :)) eye-candy.
The main reason common distributions have features similar to Windows and OS X is to make transitioning easier. Really serious people using e.g. Arch with XMonad are more efficient with very little Windows/OS X influence.
And hey, Linux could borrow those features even more easily if Windows or OS X were open source. Windows being open source would be complicated, but Apple is a hardware company and would work well enough with an open source OS at its heart.
