No, you're paying for:
Aluminum body
better screen
illuminated keyboard
8GB RAM capacity
Firewire
If you can't comprehend why that's different, then fine. It's got nothing to do with being a "Pro" machine, and nothing to do with being a fanboy or not. There's a $200 price increase to get the above features. Not important to you? Super. Then don't buy it.
So put away your BS fanboy accusation card, and relax.
Every time someone says anything remotely in favor of Apple on this damn board, they're automatically a friggin' fanboy. Newsflash, it's an Apple-centric site.
