Yes, I use the wacky Panasonic Toughbook, and I've posted about Toughbooks here before - run a search for "toughbook". The model I have is the CF-W2 - I think UK model numbers might be slightly different from US ones - go here and select "Toughbook Light" from "Product Range".

I loved my Toughbook so much that when I tipped a venti americano all over it I bought an identical replacement with the insurance money. The first one I had was 100% stable. This one seems a tiny bit temperamental - every now and then it will seize up, and the mouse pad can be a little unreliable. This makes me wonder if they're a little inconsistent - I've seen similar reports on user forums.
