Same as they do on the 'Bullfrog' laptops that they currently use in the field. Bullfrogs are made by DG-Tadpole, and tradtionally used Sparc Ultra chipsets. This order could signal a move away from Sparc, towards cheaper intel units, but all that fire-control software, and so on, runs on Solaris. (And, yes, that's 64-bit Solaris, Tom.) Since the Bullfrog carries something like half a dozen batteries in the base of a standard unit, I would expect that this will be one of the firstt upgrades this company will have to add to their unit for Navy use. Yes, they're heavy, but suck it down, soldier: Marines usually carry 130-150lbs of gear in the field.

Lenovo may argue that their semi-functional piece of plastic crap is a 'twin-screen laptop' - as may HP, their even more dismal 'Firefly' offering - but if gScreen are saying "the first dual-screen laptop with identical displays", I think the keyword is 'identical'. The 'second screen' on the Lenovo and the HP are actually part-remaindered appologies from the bottom shelves, bolted on the side of a more modern, standard display. Saying that, the civilian version of the gScreen looks almost as rubbish as the Lenovo.
