My laptop's top left corner of keyboard recently stopped working (new one shipped), and well, I've only then realized how much I use vim. I don't use it for programming, but well, it's the text editor I use the most for config files. I had to install a virtual keyboard (onboard) just to be able to press esc. So, while no esc isn't be a reason to not buy the new mbp for me (price, lack of magsafe and the dongle madness are the reasons I don't buy, though), it is still be very, very annoying.
