I've been using my MacBook Air laptop on and off for a couple of weeks now and I must say I'm suitably impressed with the Mac OS. It's turning out to be a surprisingly no-nonsense little workhorse. Though an avid Windows user for many years, I'm now finding myself wanting to reach for my MAC laptop far more often than my Windows laptop whenever I just want to just get some work done. The only thing I dislike about it is the built-in keyboard. A standard USB PC mouse (as opposed to an overpriced Apple mouse) seems to work fine for my limited needs as well.
It's not the first time I've used a MAC, but it's the first time I've actually seriously tried to use one productively. Frankly, I don't what the fuss is about with people who dislike this OS.
