Hi people. Im in the market for buying a new MacBook Air, but can't decide as to whether i should wait for Mountain Lion to be released. Im concerned because of the fact that i purchased a brand new MacBook Pro last year about a month before Lion was released, and when i upgraded to lion my MacBook became ever so slow. For example, boot times went from about 30 seconds on Snow Leopard to two minutes on Lion. The people at the Apple store said there was nothing they could do about it. What is your advice? How did upgrading your OS affect your systems? Philip.
