I have an ipad Mini and love it. Use it along with my 4 year old. Now my wife has a MacBook Air one if the early models. Core 2 1.4 and 2gb ram. We were thinking about selling that Air and buying a 32gb ipad 4. On the Air, she does web browsing, iTunes, paying bills and a few Excel spreadsheets for bill pay. Would it be a good idea to do a swap here, or should we stick with what we have?
