I concur. I love my Panasonic CF-C2. Among the features you haven't mentioned, it has a 3-end plastic strap on the back that lets you securely and comfortably grab it and hold it in one hand. It also has a small 5-minute internal battery to keep the computer on while hot-swapping the removable battery. I think Panasonic calls it a "bridge" battery. Battery sizes can also be very big. Mine came with a 70 Wh, but there are 100 Wh batteries available online. There's also quite a few removable panels that can be changed for hardware modules. I noticed a used computer online of the same model that came with a fingerprint reader on one of the panels.

Regarding its ruggedness, at least for this model, it makes the computer more comfortable than the average laptop, IMO. I don't have to worry about putting too much pressure on the screen, for example. This is semi-rugged though. There are some really rugged toughbooks that are uncomfortable.
