Unlike the Fire, Nook or Kobo Mini, you can choose an option with a 3G connection as well as wi-fi, so you can check your email, download apps, stream movies and so on wherever you are. Note that, like with the iPad mini, you need a data tariff to do this. With the Paperwhite’s 3G model all downloads are free. This is a pure Google tablet so not hobbled by any manufacturer’s whim. Great if you want complete freedom to do anything Android does, but not so good if you find the system off-putting. Still, it’s a fast, powerful machine, with the latest version of Android software on board. Unusually, even the wi-fi only version has a GPS chip so you can use it as a satnav. Versatile.
