Unusually, I'm with Iains. I have a wifi-only iPad and an iPhone with tons of data in the contract, and I can now take my contract all over Europe at no extra cost. All wifi outside the home at so-called hotspots and in hotels is utter crap, so my phone lives on 4G and my iPad is tethered to it unless I'm in the house. Brilliant. The smartest smartphones are the latest ones and they are the easiest to use, I reckon. My phone and iPad are connected to the Cloud when I'm in the house on wifi and all my photos are stored safely there for just an extra 79p a month and I don't have to do a thing. And the cameras on the latest iPhones are staggeringly good, lacking only optical zoom.
