IPad 3. Hired: Retina screen, speedy 4G internet, lots of lovely RAM. Fired: Weight. Heat. Girth. Retired: That damn battery.
Yes, if the iPad 3 were to be leaping over a fence to escape its doom, and Paris were to fire an arrow to stop it, the arrow would hit the iPad 3 in its battery charger, not its heel (sorry about the extended and twisted Greek adventure story there). Sure, the battery lasts long enough, but it takes forever to charge the thing.
Happily, Exogear’s stackable battery packs are here to help..
