I would really like it if the business plans had a feature to lock in a rate for a 3, 5 or 7 year duration. Instead of prices being subject to change whenever dropbox feels like they can push prices up. It doesn't inspire confidence to notice that your bill has suddenly changed and you're already knee deep in the dropbox ecosystem. My team really require more stability and commitment to space sizes being locked, and the rates not changing of periods of time. I think you could convince many businesses like myself to lock in to 3 year 5 year and even 7 year contracts if the rates for data remained consistent through that commitment.
