I vaguely recall Intel had some rugged convertible Classmate PC. It was sturdy and the price was reasonable but its performance was bad (like most netbooks).

Yes, but the Classmate was created in response to the OLPC laptop. From its Wikipedia page:

> The Classmate PC represents Intel's competitive response to the OLPC XO, whose unusually low prices and use of AMD chips threatened to steal market share from Intel and other major manufacturers.

It was well over double the price of OLPC, and had different functionality.

Yes, I was referring to a rugged (child proof) laptop. I think I got mine around 500 USD, not cheap, but cheaper than the Thoughbook. Hence my reply.
