I am currently only using about 200 MB for my personal account, so this would be fine for me. I have emails going back ten or so years, but those are thing I purposely kept. I never really bought into Google's assertion that I should never delete anything and just use search to find what I need. I understand that some people have way more than 1 GB of mail, but for me and other email users like me the amount of space opera is offering will last for years to come.
