After using the 13" TB MBP for the past month and reading many mixed reviews, I personally am very happy with the purchase – it's build quality is second to none, and coming from a 2011 MBA, the new 13" strikes perfect balance between weight/size and power, As I also have a LG 27UD88 (USB C with hub), I am able to avoid the need for too many dongles. BUT I am no pro user and its clear that the 13" and even the 15" are not designed for pro users. They have way too many compromises in order to be lighter and thinner. Apple need to fix its product lines. It is getting so fragmented and confusing. - The 12" MB should be called the MBA - The 13" MBP should remain in its current form but just be called the MB - The 15" MBP needs to be redesigned to be a real Pro machine with more grunt, more ports and more battery. Of course, Apple won't do any of these.
