People always get worked up about these things.. there has been lead and mercury in things for years.. the tiny amount in one of these lightbulbs is nothing.. you probably ingest more from eating fish.
in fact, after typing this, i did some quick research - FDA says average mercury in tuna is 0.118 ppm. So rough estimation, 1kg of tuna should have 1mg of mercury. A failed CFL may produce around 0.67mg over 8 hours. So if you stand there and inhale the vapours from it for 8 hrs, you're getting less than from 1kg of tuna.
The site i got this number from compares it to tuna as well (http://environmentaldefenseblogs.org...cfl_mercury-2/)
Even if you dog eats the whole lightbulb (what a dumb dog! )
thats 5mg, a very insignificant amount, considering many people naturally consume this amount in food over time.

The mercury is quite insignificant, but unless it breaks open you are nto going to be exposed. CFL lights are essentially an advancement in flourescent lighting technology, but compared to your avg. 32" or 96" tube, there is virtually no mercury at all, it's miniscule. And, modern tubes as compared to much older ones, use much much less mercury. The bigger concern is how we can safely dispose of the mercury.

As well as the electronics in the base. What I'd like to see is a separable base/tube, where you can replace just the tube.
Or, just as well, complete fixtures with the electronics built in, with just a replaceable tube assembly.

Well, that woudl be a flourescent tube lighting system. They use a *non-disposable* ballast, but it does need to be replaced every so many years. The thing is, while standard flourescent lighting systems are not pretty looking what with the gigantic bays and the ugly lenses, the technology has improved significantly from the old style. You have much better options available for eficincy, and color temeperature than in the past, the modern CFL is one form which shows this advancement in technology. But, now that LED light fixtures are getting into the market, that will open up the options even more.

There is no way they could have the same concept in "compact" forms, with electronic ballasts.

Yes, Philips does (or at least did) it with their line of early compact flourescents, which used iron core ballasts (rather than electronic).

All commercial lighting luminaires using CFL lamps have a separate ballast - magnetic (not so much anymore) and electronic. The residential CFL's use an integral ballast because of the need to easily retrofit into existing incandescent fixtures like table lamps and pot lights.

Still, there is no technical reason not to have separate lamps and ballasts, even for screw-in ballasts.
