Hm. The mock-up looks sweet. The recent Wired article suggests that it's a 10.7 inch screen, which is still a little far from the 14 inch diagonal of 8½ × 11. Works out to be 58% of full size, a little small but maybe good enough. (Assuming it's not vaporware or at the wrong price point or too breaky or never gets a large enough user base or otherwise deficient.) But I'll definitely keep an eye out.

That second comment. I feel their pain.
