And about GPU acceleration i think it's a flop, it doesn't work in all that's not supported by Apple, it doesn't work in all new stuff, it never works! I have a 9400+9600GT on my MacBookPro, and Youtube video playback runs better with the HTML5/WebM cpu-only version. XBMC is gpu accelerated with VDPAU on my nVidia GPU, but with the 9400m it runs not so well with 1080p stuff, and 9600GT consumes more power, so i don't know if it's more energy efficient an i5/i7 Sandy Bridge processor with software decoding, or a Core 2 Duo + 320M with hardware decoding.
