I can say I would like to try this bulb, but the length & heat issue is going to be a concern for some fixture applications, and safety may be a concern with children grabbing it with that heatsink base sticking out so far. I would like to see some more objective tests on longevity and how the plastic holds up to see if the life estimate is realistic...although I don't know how to test that with results coming any time soon. It is great that it is dimmable. I will wait for prices to lower...but this is the type of thing I have been waiting to see, and they should have had this as a proven, ripe, affordable technology before issuing the incandescent light bulb bans. I can't use something like this in my many built in recessed lighting fixtures. Not even the CFL will fit unless I go down to lower watt outputs. I also need dimming in a number of banks of lights which rules out CFL's. In any case, this is a very cool development that I will follow and likely try to use in certain fixtures.
