Had a Raleigh road bike as my first "serious" bike in my youth. Then, on my recent re-entry into biking after many years the progression was: hybrid -> road bike -> fixed gear conversion. The most common progression (except for the fixie) as the voting stands now. And really the fixie is, to me, just a stripped down road bike.
Sold the hybrid last month after admitting to myself I've only ridden it once since getting the OCR; now split my riding pretty evenly between the road & fixed bikes.
Maybe later in life I'll look into that Couchbike.
