I bought one. The dongle situation will be annoying for a while, and I don't know what my hybrid options will be when I get my first USB-C monitor. Hopefully it will have a thunderbolt 2 port for my older computers that I'm at Apple's mercy with (the Mac Pro being the primary example, but also the iMac).

Otherwise, it looks like a solid upgrade. I don't need the battery life and would prefer to trade it for 32GB, but I understand why they made that decision.
