I'd also be afraid of the "theoretically more reliable pure electrics" suffering from premature failures due to poor implementation, as has happened recently in other markets. Compact fluorescents should last ~6x longer than incandescents, yet since the commoditization of them, you'll find the circuits in the cheaper ones often fail long before the fluorescent tube itself would have failed (I recently did a teardown of about 20 of my own failed CFL's. About 2/3 had functioning tubes with blown circuits). I similarly lament seeing an LED traffic light or LED vehicle tail light on the fritz, knowing that the individual LED's themselves probably had another 20 years of life left in them, yet met their fate early due to a bad solder joint or blown mosfet, etc...
