For me OSX is the big win with Apple. I use Mac for live music work, it's more stable has less issues and better (music) software support. Trying to use WinXP in an environmen as demanding as a live music performance was horrible.
The old PPC Macs were very expensive for what they were, cost a lot and very underpowered... The new intel Macs are as powerful and as reliable as any brand name PC.
Before I moved to Mac, I spent quite a bit of time in the Apple store trying the machine out to make sure it met my needs... The OS felt a bit weird for about 30min as I had been using Windows for 5 years at that point... But the OS is more Amiga like in operation, and iLife gives you a complete productivity suite for free
