Pleased to see Steven still pleased with macs. To add my pennyworth my mac Powerbook nearing 6 years old (and the classic portable case still in use) is still going strong and no prob downloading upto 200 x 7MB RAW files. In PS(E4) multi-layer files soon blow up to 50-60MB, but then I use DPP and only go to PS as host for NeatImage or FocusMagic final tweak.

But if you come up with a PC as slim and functional, do let us know.
