Once you go Mac, you never go back.
I've never regretted it. The part that sucked was getting all the software I needed together -- I was no longer able to rely on my years of accumulated haxxored Windows products. Once I got all that worked out things worked great.
There was a birthday at work today and we went to a really good beer n' pizza place next to Games of Berkeley for lunch. I got hammered then walked over and picked up Sigmar's Heirs. Hooray!
