I don't always have my ipad with me. I always have my iphone with me. Always.
Ditto!
My iphone is my primary, well ONLY phone. It goes with me wherever I go. To carry an iPad around (for me) would just be ridiculous, whatever would I do with it? I don't go out and sit in coffee shops, I cant take it to work, if I am waiting in lines I prefer something small that I can just jam in a pocket quick when I am called. An example is I went to the movies the other night, a bit early to get a good seat. I have a small purse. I used my phone to entertain me til it started, I would have felt stupid toting an iPad or ANY pad in with me. If I go out shopping, I don't want to tow along a heavy tech item with me. Heavy being compared to a phone.
If you don't leave the house much the iPad would be a great go to device.
