It's not too bad. I like fixed because it takes cycling back to what it was when I was a kid. Something fun to do and not a chore. I never had to worry about cleaning or adjusting my bike, I just picked it up in the middle of the yard and rode it to where ever I was going.

I suppose a single speed would be the same, but I like the rhythmic feeling of a fixie.

I have all types of bikes (a highly upgraded Trek 1200, my fixie, and a 29er SS). Out of all of them, I like my fixie the most. It's simple, requires no maintenace aside from bar oil on the chain when I think it needs it. Quite frankly, it's a bike analogous to an old pickup truck. I never wash it, it's ugly, and it doesn't attract women... but it is reliable and it always runs, and I can repair it with duct tape and a hammer most times.
