Yes, white bike owner here too. The worst is if it happens to start raining on a ride and all the little bits of dirt and pine needle and leaf matter end up all over the lower parts of the bike. I am a little slack about keeping my bikes absolutely pristinely clean, so I don't think I'd buy another white bike. However, it's lovely when it's all cleaned up, as rare as that is!
I do think white may be trendy right now as there weren't many white bikes around when I chose that "color" for my Bike Friday (2004), and now it seems like at least half or more of every bike I look at online that I like is white or white with some accent color.
