I don't think increasing Dropbox's space by 10x is going to make a dent. When Gmail launched in 2004, Hotmail and Yahoo offered 2MB. Gmail offered 500x as much at 1GB. They made a splash with that. Fast-forward and we're now in the same place, although space is multiplied by a thousand-fold. Dropbox is offering 2GB. So launch something that offers 1TB and you're set.
