We're looking at these systems for site engineers (oil&gas industry) but from the site it seems they only can run Vista/W7.
A lot of the engineers need a boatload of old tools that might not work on vista/windows 7.
Any chance that you tried this thing with XP ? It looks as if it might work, but..
(it may just be me, but I don't think people in the market for this sort of hardware are looking for the latest and shiniest operating revision. As you said, it is a niche market.).
