Have you upgraded from your first road bike?

[7rider]

I was curious, how many of you have upgraded already from your first road bike?

How long did you ride your first one before deciding to upgrade?

What made you decide to go ahead and do it?

Well, since my first road bike was a $10 beater from a yard sale, yeah, I guess I've upgraded from that! Second bike was a too-small hand-me-down from my sister. I upgraded from that, too. Third bike was a hybrid, as I had a bad back, and needed the upright riding position. That bike was stolen, so I guess my upgrade from that was sort of forced. Went back to a road bike, and since then, upgrades have come because of:
1. The next bike was available at a price that was right, or
2. More back/neck pain made moving to different geometry pretty much a necessity.
Now, I don't so much "upgrade" as add to different niches in riding habits. Commuter, mountainbike, (dreaming of a 'cross bike and a new commuter)....stuff like that.
