Although their 1 GB of free storage sounds pretty good, I think they are a little off with the "never have to throw email away." I've got about 4 GB of off-machine backups just from the past 3 or 4 years. (Of course it's mostly business, but we're a small home office.)

We do have to have a "real" account for the business, but she frequently just forwards stuff to my "free" account for backup, so mine could still fill up pretty fast.

The "no popups" statement at the site Bill D linked is slightly at variance with other (non-Google) reports, but this is pretty new, so a lot of the "pros" are probably still guessing what it looks like.
