I tried to switch over to a mac a year ago. It didn't work, so I switched back after three months. I found that a lot of little things were annoying, and made me spend more time than I needed on doing trivial things sucha as resizing of windows. On mac it can only be done from one corner, on windows from all four. There are lots of these little things that mean you have to spend three clicks instead of two. I see why they make sense if you're a beginner - it's almost impossible to do anything wrong. Other things that annoy me the fact that it is impossible to find a lot of the little shareware programs I use under windows, and that their equivalent of Outlook really sucks. And I simply don't understand why there is only one mousebutton. That alone was enough to switch back.

Overall my opinion of macs is that they are excellent for beginners, and for looking cool in the cafes but for me it simply didn't make the cut for serious work.

I don't code, but work in outlook, excel, word and a browser. This might make make a difference.
