That word gets our attention: FREE! Jim Hamm notifies us, "If you use Gmail for your email client, here's good news: you've now got 15GB of storage -- up from 10GB previously."
There's some Unified Cloud Storage for FREE across Google Drive, Gmail and Google+Photos. After the first 15GB the upgrade plan starts at only $4.99 a month for 100GB. The next couple of weeks brings the staged roll out.
