I've used flourescent bulbs for ages - they very rarely burn out in my experience. I bought some really cheap ones (Asda 'SmartPrice') and 1 of them didn't work but I took it back. They save so much power on your electricity bill (and less CO2 for the planet)

It shouldn't be to long before we start seeing the newer cree dies out on the market, in the 5w range with a nice 60 lumens per watt range. I am not sure exactly what the trade off is since they put out so much more light per watt, but the 5w compare to a 11w CF on one die. They also are much more conducive to being a true flood like a normal light, at least emitting in a 180 pattern from the die.
