One part is, I guess, the seamless upgrading (when I use Firefox, I usually click on "upgrade next time", because I am always doing something TOTALLY important that can't wait). Other part is that the extensions don't break every new version and the UI looks completely the same (unlike for, let's say, Opera, which changes UI all the time). I don't know what browser version am I using, and I don't care.
Really, I hope this will become standard in OS, too.
Woo!
Or reassuringly stable if you are supporting an enterprise. Given Google's planned abandonment of support for older browser versions in their applications, there may be a ready market for a more stable browser platform.

These are all admirable goals and Chrome's versioning is just a side effect of newer software development methods. Chrome is perhaps on track to win the browser wars because it's the best browser and gets new features the fastest; IE's release cycle is still humiliatingly slow.
