If two heads are better than one, does the same apply to screens? Sony clearly thinks so, because its forthcoming S2 tablet boasts not one but two touchscreens. So is the S2 a gimmick, or a gamer's perfect portable? Let's see. The Sony S2 specs are interesting While most of the Sony S2 specifications are fairly typical - dual-core Tegra, Android Honeycomb ( Android 4.0 Ice Cream Sandwich has been rumoured , but that seems unlikely), twin cameras - it has one very big and very obvious extra: a second screen . Instead of the ten-ish inch screens we've become familiar with, the Sony S2 has a pair of 5.5-inch touchscreens. That makes it more portable than most - you can fold the S2 and chuck it in a pocket - and it also makes it more interesting than a typical tablet. The S2 is said to be available only in a 3G + Wi-Fi version and will come in 16GB and 32GB variants. The Sony S2 features could depend on what you're doing As we reported in our Sony S2 update earlier this year , the Sony S2 features could vary from application to application: because the twin screens can operate independently the Sony S2 could split media between its screens, or it could use one screen for controlling the other, or games could use one screen for action and one screen for maps, inventory and so on. It'll be interesting to see how that works with movies: will you have to squint at a single screen, or put up with hinges halfway across the picture
