Yeah, we tested a couple of those at work. Have been using Panasonic Toughbooks. The cost for what we got was quite a bit higher then Panasonic's, but they were easier to load.
I have just not been able to justify the cost of those. We have had the regular dells out there on the road in and out of pit carts and thrown all around for years. I guess if I was in the desert or a really bad environment I could see the cost justification. I can buy almost 3 LT for what one of those costs.
