I bought my first "serious" bike late last December, and I'm afraid I'm starting to go into the deep end of "bike mania". The funny thing is, at first I couldn't even fathom what the difference was between a brand-name bike and a department store special and was loathe to spend $700 on the Trek hybrid I eventually bought. I was only planning to piddle around town, but then my hubby dragged me with him to the dedicated cycling roads near our place where roadies in cool gear whizzed past me at jet plane speed. I wanted their gear and their speed! I have since bought SPD shoes and pedals, and I'll be changing to shorter cranks this weekend (I feel my 170 mm cranks are too long as I'm pretty short in height and inseam).
I'm still woefully slow compared to your regular roadie but I've been making progress: average speed has remained more or less at 18 kph but I can now ride 42 km without feeling like destroying every muscle in my leg. I'm still terrible at any incline though. Improving but not by much.
I'm frothing at the mouth thinking about the proper road bike I'm going to buy...one of these days. N+1 ftw.
