"Oh, you want to hook your Firewire drives up to it? That's another adapter. Oh, you want to play or burn CD's? You need to get an external drive then. You want to use your old Magsafe power bricks? Sorry, we changed the connector. You want to lock up the computer while it's at your desk? Sorry, there's no Kensington slot anymore."

At which point the SSD and Retina display sound nice, but that other stuff seems like it's going to a pain in the neck on a daily basis.

Apple tend to deprecate and remove stuff often and quickly. The PC world and Microsoft don't. For those of us who like living on the cutting edge, we're fine with it, but it's not really for everyone.

Remember when the iMac was the first USB-only computer, and had no floppy drive? Both were really unpopular at the time.

(Lack of Kensington is stupid though, I'll agree on that.)

It's not thick enough to fit a Kensington slot unfortunately.

Ah, so that's the reason. Apple's relentless pursuit of thinness is nice, but it has its drawbacks. That's also why it lacks Ethernet, AFAIK.
