The iPhone is not at the top of the Windows share, it is a non-Windows mobile phone that exceeds the Windows share.

Yeah, it's a misplaced modifier. Perhaps more clear would be:

Apple surpasses Microsoft in race for share of smartphones.
or
iPhone surpasses Windows Mobile in race for share of smartphones.

I presume all of the flavors of smartphone OSes from Redmond (Windows CE, etc.?) are all lumped together, and iPhone still has the lead?

Personally, I'd be far more concerned with ID fraud than attacks on the encryption scheme. How do they determine who's using the 'hardened laptop'?

Maybe they do the same simple thing that we do at the good old fashioned polling place where I work each election in King County, Washington. Before we allow them to mark a paper ballot with a pen (or step up to the electronic machine, if that's their preference) we ask to see their government-issued ID. Your state election laws may vary.
