Unless you're checking email headers, you just might not know if you've received emails from people using an iPad. I send dozens of emails weekly from my iPad 1, both directly through the Mail app and through online apps like Desk.com. And this is doing real work: tech support, dev communications, and more.

And TV? I think I watch video on my iPad perhaps once every couple weeks. And then its likely just a 3 min Vimeo clip. My iPad is absolutely a work device; it's in fact my full on-the-go work solution.
