I'm a mac user. I got one in a fit of technolust a couple of years ago and ended up noticing all the things that xp did that osx wasn't doing quite as well (at least it wasn't fitting the workflow that I'd become accustomed to. A workflow that had been defined in part by what windows had permitted). I won't go into a lot of details in order to avoid a flamewar (I'll mention 2 examples at the end just for fun). However, recently I became tired of using Parallels because it's such a resource hog (not it's fault, just the fact of running 2 OS's side by side) and decided to make a concerted effort to go All Mac. And then I was able to understand why the Mac is a better platform.

The Mac has a different philosophy to it. One of unification. All tasks and s/w can connect naturally to others.

Applescript and Automator are the epitome of this. If you want proof of platform productivity these tools are it. These things are impossible on Windows. It's actually been quite eye opening for me to begin to have a whole new relationship with my laptop. And I should add that I've been a developer for 6 years so I'm not computer illiterate.

That said, there's no browser for OSX that is half as good as Firefox on xp. The extensions for FF are fantastic. Also, there's still some s/w that has better tools for windows than osx (Salesforce for one).

Good Luck. Get the MacBookAir and make us all jealous. Overpriced but gorgeous!
