Panasonic Toughpad FZ-G1 with iKey FZ-G1 Jumpseat Keyboard attached. Like a tradition, I never even saw windows booting on this machine, because I installed Fedora 23 in two minutes to SSD.
First time for years, I felt like carrying some serious set of hardware, mainly due the weight of the combination. 10.1" screen gave me an 1980x1200 resolution which is pretty small print. After tweaking settings of GNOME3 to suit better, this device turned pretty awesome.
Toughpad itself is IP65 but keyboard is not specified to any IP ratings. Keyboard is whole rubber and I bet it stands some elements, but without any official IP rating.
We are working on a project where we utilize FZ-G1 and I probably will be able to share some details of it later on.
