My feelings for Mac has been mixed, I haven't found it much superior to Win 7 (to warrant the apple tax) and there are things which have annoyed me (e.g. different shortcuts for doing the same thing in chrome vs. firefox. Some apps having a full screen mode, some don't.)
I agree with the author that Exchange and chrome works(though flash causes it to break often) but these work on Windows too, so these are not things I would want to pay extra for.
I haven't found much in the software to pay extra for the Apple experience, if I do buy another Mac it'll probably be due to better hardware than anything else (but I cringe on the thought that I can't upgrade the RAM/hardware myself though the iMac looks really nice on my desk)
