For the money, the Sony F is amazing.
Not sure I'd futz with Hackintoshing it though. But if you're cool with running Windows 7 and need the quad core to render and compress things, go for it.
One thing though, I had one and returned it. I thought the vertical viewing angles were just too awful to live with. Also, I was not not feeling on the 1920x1080 res, this 16:9 trend blows. The screen is a personal preference thing, it may not bother everyone, and it did look good within its limited viewing angle.
Also, the quad i7 is hot chip. Sony did a good job with the fan, but the fan will always run, and when you go to peg all 4 cores, the fan will definitely speed up and be pretty audible. That's not Sony's fault, it's a hot chip, any quad core i7 is going to have to run the fan pretty high.
Otherwise, I rather liked the Sony F, but am generally happier with my new 17" MBP, though it lacks the quad core and has 512MB VRAM. The Sony had eSATA built-in, which was nice.
If you need the power and can live with the screen, the Sony F is it.
