I'm selling my Panasonic Toughbook CF-U1. This is a tough portable PC you can stomp on or wash under the tap and it just keeps on going. Google it for more info and pictures. It runs Windows XP (Win 7/8 also work) and is fully compatible with Windows applications. This is the model with one gigabyte of RAM and I have upgraded it to a 32 gigabyte SSD. The SSD is easy to swap over and I'll include the original 16 gig one so you can have Linux on one disk and Windows on the other if you wish.
There is a mark in the corner of the screen (a dark spot on the outer plastic) and a couple of cosmetic scratches to the outer casing. Otherwise, it's in good working order. Both batteries and the mains adaptor are included, also the stylus and hand strap. I'd like to meet face to face in London.
