1) Nobody wants to hold their iPad up to their head.
2) On the other hand... what's stupid is walking around carrying _both_ a cell phone and an iPad!
3) So I've said for years and years.... what we need is for Apple to offer some kind of iPhone/iPad option hybrid. I'm 50 years old and I can't even see anything on my iPhone 4S anyway without my reading glasses. But if my new iPad Mini came with some type of Bluetooth solution all bundled in place... I could use that all the time. When the phone rings, you pop the earpiece on and push the button. In the car, the Bluetooth in the car picks it up. Etc.
It really does seems amazingly redundant to buy an iPhone and then a cell version of an iPad. Why can't I use the cell version of the iPad to make my phone calls??
