I was told by an SRE on Drive that the unlimited offer was legit because the at the rate you could upload data to drive the costs were still far bellow the bill. Of course that seemed wrong because if you are uploading for years $5 a month isn't going to keep covering all of that storage. I imagine that part of this assumption that storage costs would keep dropping and presumably this isn't happening as quickly as originally predicted.
