I don't care, it's encrypted with a password that is twice as long as this sentence. I can host it in public, nobody's going to get in without knowing my ridiculously long and convoluted password.
It bothers me that there are people that don't understand just how secure and easy Dropbox + Truecrypt is. EVERYONE should be doing this, and no one should be using online wallet sites, anymore. I just wish someone would make a Bitcoin client that didn't require 1 gig of space and let you set transaction fees lower than .01.
