My problem with ultrabooks is what is intel doing with the brand. At first, ultrabooks were supposed to be laptops with good battery life, high-resolution IPS screen and a SSD. Also it should be thin, which I think is meaningless, but whatever.
However, it seems that this disappeared somewhere, and now laptop with 1366*786 15" TN screen and rotary storage (with a measly 16 GB "SSD cache" that does pretty much nothing to make it faster), but it is required to have Windows 8 and touchscreen.
The brand lost meaning, it went from "Apple quality from someone else than Apple" (so we can buy nice computer without supporting walled garden approach)
