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 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?
Sony isn't letting anyone near the damn thing
When Sony showed off the Sony S2 tablet to the press earlier this month, nobody was allowed to see it in action. "We were only allowed to eyeball the lifeless slate from outside the confines of a perspex box," we duly reported back. Our impressions? "It didn't seem much bigger than a Nintendo 3DS".
The Sony S2 release date is in September
Like its sibling, the Sony S1, the Sony S2 will be available in John Lewis, Sony Centres and no doubt the usual online suspects from September. However, while the Sony S2 release date is in September, we don't know exactly when: you'll be able to pre-order the S2 from 1 September, but Sony hasn't said when you'll actually get to take your shiny new tablet home with you. We can't imagine you'll have to wait long, though, as Sony won't want to lose any sales in the incredibly lucrative pre-Christmas shopping season.
The Sony S2 UK price probably won't be cheap
The S1 price hasn't been announced yet, but Sony is a premium brand and the Sony S2 specs are pretty hefty, so we're not holding our breath for Tesco Value prices. Early rumours suggested a price in excess of £500, but Sony won't be drawn on that just yet. It's probably a good idea to start saving, just in case.
