How do those survey thingies work?

There was an attempt to find things in common with those who have the lurgy, as Neil says, what do the unafflicted have in common?

My MC200 is a late one, my iPad a v1 running 5.1.1. Control:Mac 2.394 (build 315).

Maybe it's 5.1.1? Anybody that annoyed they want to swap for a v1 iPad?

I have to say my iPad crashes a lot (I think I'm in a minority there, otherwise I'd be moaning more).
