This is in response to Jon's article in the Sep 2010 issue:
When thinking of an ideal laptop for me(PhotoShop/Lightroom), I have two scenarios to optimize for: On the road and back at home base. This is why I've settled on the Dell Precision M6500 as my choice: i7 quad processor, up to 32 GB or RAM (16 seems to be the sweet spot), up to three hard drives, a good graphics card, and a good LED display. PhotoShop will gobble up all the RAM you can throw at it and if you have three drives, you can use one for OS/programs, another for data, and another for the scratch disk.
For the home base set up, the selling point for me was the availability of the E-Port Plus docking station: you have both 2 DVI ports and two DisplayPorts. Multiple monitors when you're doing your final preprocessing. (As far as I can tell, this is the only place where you can get this dual monitor capability in a reasonably priced docking station. I know there are docking station options that will let you use a VGA and a DVI port to get multiple monitors. But for graphics work, you should have your monitors set up as identically as possible.)
If another option comes along for simply attaching multiple monitors to a laptop, I'll look at other hefty mobile workstations.
