Recently came across this new, dropbox-like service which gives 15GBs to start for free. Since they are new, they are also giving out 5GBs per referral, which is also much more than Dropbox gives.
As a current dropbox user, I always look for ways to get more storage, and currently own a Dropbox Pro account. I use it religiously to securely share sound files with clients. It's a great tool to do so. With Copy, they seem to be giving me more bang for my buck (even if free! haha), and will be testing it out to see if it can be a viable replacement.
If you would like to check Copy out for yourself, you can do so here. Let me know what you think!
