well i have:
my trek 6500 for XC trails

My cannondale roadwarrior 400 for commuting /touring (panniers and rack)

My fuji roubaix pro for fun road riding (fast)

But the next purchase will probably be a better road bike, full carbon looking at SRAM rival or up. looking to spend 2-3000 but it probably won't be for another 2-3 years (the fuji is less than a year old, but would be a backup rain road bike)

My next real purchase will be a nice wheelset 400-500 sometime this fall or winter (i already warned the fiance, it will be a reward for <200 if i get there)
