My only disappointment from the keybote - AirDrop
I really don't understand how Apple could omit AirDrop from OS X to iOS. I was really looking forward to that! It's the one thing I miss most from Android, being able to quickly and painlessly transfer files over Bluetooth between my Macbook and phone.
Ah well, can't complain too much, free Mavericks upgrade! And I will see how long I can hold off from buying a new MacBook Pro.. :)
