I absolutely love meerschaum pipes. Over the past 2+ years I went from owning 2 meerschaum pipes; to currently having 15, with another two on the way (a gourd calabash with meerschaum bowl, and an H. Cor Hawkbill). Over the last 2+ years I went from smoking them about 10% of the time to the 90% of the time. I love the look, the feel, the way the pipes smoke cool and dry and the taste of the tobacco during the smoke. For me it doesn't get better than a meerschaum pipe.
For those that believe they're to fragile; I smoke mine outside, on the go, and I travel with them. I handle them like any other pipe, and don't have any issues. Yes, if you drop it on the hard ground it will most likely break, but if you drop a briar pipe on the ground it can also be damaged. Chances are it won't be in pieces though. The figural pipes are going to be a bit more delicate depending on the carving, but the classic shape pipes are pretty solid. As for durable, when it comes to smoking them they're more durable than briars in my opinion. I can smoke my meers all day long every day of the week without issue, but I can't say the same for my briars.
It all comes down to preference, and they're not for everyone but I think they offer the best pipe smoking experience. With that said, the month of March is March Meerschaum Madness. Its a chance for those that rarely pull their meerschaums off the rack to smoke them more and really experience the pipe. So get out those meers and smoke them!
