We love Dropbox, and it takes the lion's share of votes again this year. It's also great to see viable alternatives with a decent following. Will Dropbox continue to reign supreme, or will features like SpiderOak's baked-in encryption motivate folks to switch? Dropbox is certainly our incumbent, but with cloud-based storage being such a new market, it's exciting to see what the future holds!
