Not sure how that quadcore compares to the MBP's, but I got dual 320GB harddrives just for good measure. Not LED, but I'm pretty sure the color gamut exceeds the MBP aand I threw in the Pantone color sensor for easy calibration... and I like black computers more than two-tone or silver.
This is a starting point - you can add a lot more to this in terms of processing power, 3G SIMcard slot, WiMax, slide-out 10" screen and Quadro FX 3700M 1GB graphics card. It may not be skinny and light...but it kicks butt
