Like many, I'm somewhat intrigued.
I've been browsing around town at several LBS's, and as expected there are wide differences in atmosphere and inventory, etc.
I can see why so many do like fixies - they're often quite attractive to look at. In my case I got taken by a yellow Masi Speciale Sprint, although I would have to insist on a second hood/brake lever lest I forget, reach for a non-existent hood by mistake and wipe out.
The price tags are generally attractive - seems that about 600-800 MSRP is pretty common, and that's a lot more affordable to my way of thinking than 1500 on up.
So, the $64,000 question:
Can a fixie be a good option for a re-entry road/Clyde? I think a steel frame is a good thing, and simplicity and all that is also good, but, but.....no gears?
Is it difficult to change rings? Same chain or different one required? Or does this depend more on the dropout design?
I do live in a slightly hilly area, although once I make it up to the top it's pretty flat all the way across town. I eventually intend to get a bike rack, and that would add a lot of flexibility, but running around with a bike strapped to the back of the car does use gas, and that seems somehow a bit self-defeating.
Come to think of it, any reason NOT to get a fixie now and a roadie later?
