Google has always been about cheap (even free) storage. Initially Gmail had a gigabyte of storage. Unbelievable! Then Google raised the bar. Now the storage is over 7 gigabytes. This was used for Gmail and Picasa Web. If 7 gigabytes wasn't enough Google would sell you more. An extra 10 gigabytes was $20 per year.
Now Google has doubled the storage to 20 gigabytes and dropped the price to $5 per year. For the old price of $20 per year you get 80 gigabytes!

Pssst! Can you say Gdrive?
