Well, I like to compare the price of Mac's office and Mac's development kit ($0) to Windows' (>$1000
each).. that's a good way to make a decision right there. Any company that expects me to pay over $2000 to be productive, PLUS the computer and OS, sucks.
The only real incompatibility is games; and they're getting better. A lot of games lately are supporting Mac and/or Linux. The only thing I really missed about Windows was having a Battle.net bot, and I fixed that.
I really can't stand using Windows anymore. I had to use it for awhile today, working on a group project, and it's sooo painful. I don't know how anybody can STAND using it, unless it's all they've ever known. But I feel so tied-up and gagged while using it!
