If you break one, I hope you are not carrying it and it isn't  full.  I just don't see the advantage and the disadvantages are too great.[/quote]
I like glass.  I do have a couple of plastic buckets as well that now serve cleaning/sanitizing duty.  Glass is non-porous (oxidation), holds temp well, and does not scratch or discolor from repeated cleanings (places for bacteria to hang out).  I can't say the same about plastic.  That being said I have not broke a carboy yet...if that happens I will reevaluate my thinking as I'm getting stitched up.
