My work just recently gave us all hp elite book 12 inch laptop/tablet hybrids. I hate the size. I am having a really hard time being productive on the small screen. 1 inch does not seem like a big difference but let me tell you it is huge if you have bad eyesight, and need to type long form reports like I do. Personally I wish they would go the other direction and do a super thin 14 inch laptop. For me that would be the perfect balance of portability/productivity. Even if the new air is as thin as 2 sheets of paper, with a 4k retina display I will not buy it. Who else needs at least 13 inches to be satisfied?
