I have broken at least 6 carboys. One full of 8 month old barley wine. Back in the day it wasn't such a big deal (except when they contained barley wine), now that they cost about 45 fricken dollars at the LHBS it is quite a big deal. Started using plastic milk crates but some of my carboys don't fit in them very well. I also use a Carboy Hauler. I actually broke another one this summer. It slipped out of the Carboy Hauler. I now use buckets as often as possible.
I do have a very ncie collection of beir steins, several logoed belgian glasses, a couple of stemmed doppelbock glasses, several stangs, several weizen glasses, etc. The thing I am really hard on is pint glasses. I am down to one Imperial Pint glass and one 1/2 Impy. Last year I had several. I do have my "Favorite" Pint glass (which is just a logoed tumbler my sister got me at a brew pub out in Oregon a few years ago). I just noticed the other day there is a chip in it. I had one that looked just like it, but I broke it.
