I don't know about your situation, but the laptop I take to the track for data acquisition/analysis is living on borrowed time. Whether parked on top of the pit cart, balanced on the racecar, or fighting for workbench space with cups of coffee, it's an accident waiting to happen. At which point all that irreplacable data will go away. (Of course, I always back up my data. Yeah, always. Really.)
Well, here's the answer - Twinhead Corporation's Durabook N15RI. Magnesium alloy case, antishock protection for the screen, motherboard and hard disk, and sealed, spillproof keyboard, speakers and touchpad. Otherwise, it's a normal Pentium-M or Celeron laptop. Prices start at $1500. Cheap insurance, really. And you'll wow 'em at Starbucks when you slam this baby down on one of those dinky little tables.
