I am looking to get a core i7 laptop in the next 4 - 6 months ... ish ... (well to get money AND in the hope the specs i want might become available)

I know the combo i want wont be available (or at least affordable!), in order of priority
- fastest CPU - core i7 3GHz x4 before turboing would be good! heh heh ...
- lightest 14 - 15" size (dont care about resolution)
- bluray writer
- longest battery life (doesnt really matter, but just curious about graphics card vs none)
- HDMI non negotiable

so - would one go for something like mobility HD5650? or no graphics card at all to "save power"? i've heard some mobos are able to "turn off" the graphics card to save power?
