I know this couple and they both have these old school flip phones that look like the phones that I used 8 years ago and they carry around iPad 3's and they pay for the data plan and they use their phones for calls and use the iPad 3 for everything else. I'm curious if anybody does this with an iPad mini. I thought these people were nuts for carrying around their iPad's everywhere but now that I can fit my iPad mini in my jacket pocket it's actually not a bad way to go. You can use your iPad mini for text messaging with the Google Voice app. Right now everywhere I go I take out my iPad mini and use my iPhone 4S as a mobile hotspot. It actually wouldn't be the worst idea to get a data plan on my mini and just get one of those flip phones. I barely use my iPhone 4S anymore except as a wifi connection.
