Dropbox Doubles Capacity, Leaves Prices Alone; Also Adds 500GB Option
Lest your dander rise at the audacity of Dropbox to automatically do such a thing, note that the upgrade is free to current Pro account users, and any new sign-ups will get the same deal. This isn’t a temporary promotion or something; it’s a permanent change.

Although it’s as popular with average users as can be, Dropbox needed to make such a change. Prices for cloud storage are falling like rain in Seattle, and this new deal ensures that users stay put and new customers join up. For good measure, Pro users can share a three-month trial of Dropbox to share with that special cloud storage-less someone in their lives.
