I have been somewhat reluctant as well. My sister had tried to get me on Dropobox before but I wasn't interested. Then just after I got my Vox my nephew sent me an invite and I thought maybe I should try it out. With the Vox it makes so much sense to have all the apps where I can get them anytime. I am also keeping my "Master" and "Working" book collections on Dropbox.
I probably will not keep the directions to my box of gold on the cloud however.
