It's a fine line for sure. I recently recommended ChromeOS for my mother. Her problem is that she runs programs that compromise her OS. The malware I've removed from my parent's computer is hugely invasive and it is usually tied to her account. Given the choice of Google having some of her privacy details or some unknown crackers, I'd much rather have her expose that information to some cooperation that has public scrutiny over how they handle that data.

Heh, I got one for my wife, cause all she used her computer for was Facebook. Who gives a shit if Google gets all that stuff now too, Facebook already had it in their datacenter.
