Linux (Fedora 18) works a charm on Dell Precision laptops, powerhouse machines at that, can go 32GB RAM like Thinkpad 530Ws, and 3X SSD if you're so inclined (probably coming in sub MBP price to boot). Had some hiccups with previous Sony Z-series laptop, but one nice thing about switching machines with Linux is that X11 config settings for your peripherals (trackball, wireless KB, etc.) all apply to the new machine. The biggest headache has been Nvidia, forcing max power consumption (and heat generation) with multi-monitor setups (of course, IIRC that affects all laptop makes, Macs included). Fortunately Dell Precisions have 2X fans (CPU & GPU) so cool & quiet overall, just not a big fan of Nvidia, would have a near passively cooled machine were it not for the multi-monitor max power issue.
