I've thought about it but I decided the number of flats I get didn't warrant it. I also would probably not be disciplined about checking sealant regularly.
Lastly, I've had two side wall blowouts and I don't think Tubeless would have helped me. Probably would have just spewed sealant everywhere.

Discovered this one yesterday after returning from a 40 mile ride. Tube protruding more than a quarter inch out of the tire. Quite surprised it didn't give out. This is a Specialized tire that came with the bike. Has less than 700 miles on it.
