is that toughbook the PIII that was crushproof that was for the millitary or something?
another thing you could do is get a Tablet PC and a waterproof case from Otterbox. it also has "Drop protection"
here is a link: http://www.otterbox.com/products/pc_...blet/index.htm
its for fujitsu tablet computers. that would be a pretty good option for you, as there are few options, and if the toughbook is what Im thinking it is, it costs $4,000 and is very dated and slow.
here is a pic for ya:
guess the toughbook isnt what i thought it was. looks pretty nice, but expensive and pretty big and heavy compaired to an otterbox case.
