Quite true, although most of the other replacement techs have some big flaws. Like CFLs; a LOT of people I know can't stand the way they light, they often don't fit into covered fixtures, etc.
I'm not sure we would be having this conversation a few years from now. Another couple years with manufacturers knowing what's coming could really drop the price to the point where people wouldn't care. I think the fact that there's one lightbulb up for the prize when there's a bunch more manufacturers tells a big story. It's already been established that prices for LED bulbs are expected to drop drastically over the next few years.
I know nothing is guaranteed, but it's fairly obvious LED tech isn't quite ready for mass consumption, and that seems to be the tech with the fewest flaws going forward.
