I'd also like to mention that this discovery changes conventional views of the interactions with magnetospheres and the solar wind. Even my comment regarding the polarity of the IMF seems to be no longer valid. So all bets are off.
A bit more clarification may be in order. The atmosphere is our primary protection from high energy particles. We would be protected from high energy particles if the magnetosphere were not present. However, as you say, without the magnetosphere our atmosphere would gradually blow away (you're correct that Venus is not a good analog, but it was easier than going through the whole thing about when Mars' magnetosphere may have gone away). Of course, if our atmosphere goes away we won't have to worry much about the effects of cosmic rays, we'll be back to living in caves (sealed).
I have no doubt that we are going to be learning a lot more about the solar wind et al. We haven't been out there touching it for very long at all. Science!
Urm... wouldn't we be dead if we lost our atmosphere ? - I mean.. whats the point in becoming a troglodyte if you have no air to breathe ?
hrmm..
