Wi-Fi hot spots are popping up everywhere public and private while mobile broadband is developing by leaps and bounds.

Dirt can get into ports, liquids can spill onto the keyboard, and pin connectors can bend.

Most don’t have handles, are flimsy, brittle, and have narrow operating temperature ranges.

They meet military standards of reliability but weigh more than some desktops.

you might find notebooks with acceptable operating temperature range of 32 F to 95 F listed by pricehere.

They are fairly priced and you could add a soft or hard shell case.

But where do I find rubber plugs for the ports and how do I protect the keyboard from spills?
