All of your security fears could easily be addressed. No need to get into them, but I thought such functionality would be cool and useful.
"Here Johnny, take daddy's iPhone and go walk around the mall. I'll sit here with my iPad and keep an eye on you."
What about Find My iPhone multiple user functionality?
I still find it funny that I can run Find My iPhone...on my iPhone.
My wife also has Mobile Me and it would be cool if I could punch in her Apple ID to find out where she's at. (But she should add me to an approved finders' list on her end, however.)
Such a feature would make that show 'Cheaters' much more appealing. And do away with having to hire a PI. Not that I would know.
I don't care about market share, units shipped, etc.
SHOW ME THE MONEY (I.E., GROSS PROFITS)!
Wonder what that tables looks like then.
One Apple iPhone makes Apple more money than 10,000 Jitterbugs sold in Florida, so who cares about unit shipments.
This is done on the stanchions of high-performance mountain bike suspension forks and the body shafts of rear shocks.
Pretty cool stuff. RockShox has their own nitriding machines out in Colorado; huge bastards! Fox Racing Shox also does this new one called Kashima Coat, from the Miyaki Coporation of Japan.
Fox Racing Shox is about a half hour's drive from Apple HQ. What a logical corporate connection: mountain bikes and computers.
