Fujitsu makes some outstanding 2-in-1 machines, including terrific displays with rugged dependability. I have bought them for my girls since they came on the market, although the long life means that we are only on our second one for each.

I am not sure that Fujitsu is aiming for the consumer market with these, as they are equipped and priced more for the corporate environment, but if you can afford it, they are worth the price of admission.
