CFLs are improving in leaps & bounds. 3 minutes let alone 5 is, IMO, not applicable to the current ones. I'd say they come on at around 80% of their full output, which they reach in less than a minute. That's how they feel, subjectively.
Long term, anyway, has surely got to be a wide range of luminaires with the control gear built in, HF for efficiency, dimmable, taking basic fluoro lamps, (and I can see the need for a few new, smaller, sizes), and avoiding all this waste of electronic components each time a CFL is chucked away.
And induction lamps - I'd love to see those become common. I've got some in my kitchen, and they're very good. Not cheap, and as they age they do get slower to ramp up, but there's no way you'd ever complain about the quality of the their light.
I want to try a couple of the dimmable CFLs - in my living room I've got 4 wall lights/uplighters which take 100W GLS lamps. They're on 2 dimmers, so I was going to replace one pair with CFLs and see how they are.
