Dropbox pretty much runs my world - home and work.
Should I start looking for an alternative?
OneDrive or Box ?
You want to jump ship because some members of an internet forum are making gloom and doom posts about the future of Dropbox? I see you haven't been a member here long, you'll eventually get used to the pessimism on this site.
Dropbox also "runs my world" and there's no better alternative (for me) out there. I'll worry when there's actually something to worry about.
