Kegging is nice in that you only have to clean/sanitize one, er, "bottle".
You can also force carbonate if you don't want to wait the two weeks for the sugar-priming. Beer faster!
We went from endless bottles to two kegs and a single CO2 source in a chest freezer with a temperature loop controller. Bit of a cash outlay to set up, but if you're going to stick with the beer as a hobby, it's sooo worth it.
