Oh jeez... I've got 2 mountain bikes, 1 road bike, 1 'bent (that I need to unload, just didn't work for me), and a 26" wheeled scooter w/ suspension fork. Other half has 1 'bent, 1 mid-70s Peugeot road bike (awesome ride), 1 road bike, and 2 mountain bikes.
I just got my Ibis Mojo out of the shop from it's yearly off-season overhaul (got a new front wheel on warranty, yay!), and am waiting until post-holidays to take my old backup Marin in for the same since the fork is clunking in the frame and I can't get it tightened up. And the derailleur I had to bend back. Is that bottom bracket creak? And a half dozen other things I've thrashed over probably 2000+ miles on that thing....
Fortunately we've got access to an excellent local shop, and the $$$ I've spent with them has been worth it. The guys tell me I wouldn't wear out stuff if I'd quit riding so much....
