I bought the machine, putting thoughts reservations about screen (too shiny) and keyboard (too tacky) aside. I love how fast it is compared to my old, very old, model. It looks great. I installed Yosemite without any issues. Am still getting used to the new look but I'm sure that will happen. The screen isn't quite as glossy as I feared but I still am sometimes startled by my own reflection when I'm working. The chiclet keyboard is ok, but I doubt I'll ever be a fan. On the whole I don't regret the purchase. It's a pound lighter than my old one but I think that comes at too big a cost -- I really don't like how inaccessible its insides are, the way everything is soldered and glued together. And, following the imperative to make everything thin, there's no room for a kensington lock or a remote control sensor. It's as if the MBP has become another iteration of the Air
