Three words for the crowd that actually believes "McCain can't use a keyboard because of his POW injuries":
PROFESSOR STEPHEN HAWKING.

You want to talk disabilities? Those are disabilities and it hasn't prevented him from keeping up with what's new in the world.
McCain can't use a computer because he's lazy and has no intellectual curiousity about a system that has become a major part our world.
Intelligent people have a curiosity about and learn new technologies.
Ignoramuses rely on others to do for them.
Unfortunately, some people revel in ignorance and consider it a virtue in someone else.
BTW, if someone has the bright idea to piggyback that last sentence to try to be clever and attack me, a simple thank you would be appreciated. And y'er welcome.
One last thing: If anyone wants to email Professor Hawking, there's an email address given on the website so you can do so. The man with ALS figured out a way, but John McCain can't.
