Yeah, it's too bad my refrigerator won't let me make emergency calls, either. Nor will my vacuum cleaner. What if I'm in the middle of my living room vacuuming the carpet and have a heart attack? The vacuum really needs a built-in phone.
Maybe they need to put a phone in my dog's collar, too. I could have a heart attack while out walking my dog.
For that matter, my skis should have a cell phone built in, too. Just think how hard it might be to get help up on a ski slope if something happens.
The iPad isn't a phone nor was it meant to be. Granted, with Skype, you can use it to make phone calls if you have a WiFi connection, but that's not its main purpose. If you need a phone, carry a phone.
