After not owning a dell for years, I just bought one for the kids to use shortly before the news of the security issue came last weekend. Frustrating!
It hasn't really taken off, so it appears that people don't highly value such safety.
Edit: I'm not defending Dell in any way, but if they're watching youtube and browsing facebook, they'll probably be just fine.

Email accounts are interesting for spammers. Reason enough to want working https.
