Macs are kickass computers my friend. I personally use a 17" macbook pro and use a new 24" iMac in the office (these aluminium cases rock). I can say that you've made a great choice. It never crashes, never leaves you on the half way and works perfectly for a very long time (when compared with pc's). Mac OSX Leopard is also 10 years ahead of Vista. You'll love your computer more and more everyday.
Welcome to the wonderful world of Apple mate. I salute you.
You can ask me whatever you want.
