Why I stopped using DropBox.

I received an e-mail from DropBox saying, "We noticed you're not taking advantage of your Dropbox account." I wanted to explain why, but it came from a no-reply address.  This is the only way I could find to send anything.  

I used to use DropBox a lot.  I liked it very much.  But then you restricted the number of devices to three that I could be logged in on at the same time.  I had three computers and two cell phones.  After you made that change, I started using GoogleDrive for sharing particular files across my various devices.  

I don't know if you even still have that restriction.  But that's the reason I stopped using DropBox.
