Unlimited Free Gmail a Thing of the Past?

Google is now offering extra storage space for Gmail and Picasa, but for a price. Sounds a little like Apple's .Mac storage offer to me. Anyway, here are the details:

6 GB for $20.00 per year
25 GB for $75.00 per year
100 GB for $250.00 per year
250 GB for $500.00 per year
