The Metro UI on Windows 8 looks amazing, and should be incredibly well-suited for use on tablets in its Windows RT guise. It will, however, cost you if you want to give it a try.
VR-Zone is reporting that Microsoft is planning to charge OEMs an average of £55 per Windows RT install. Compare that to the cost of an Android install — which is, um, free — and it's obvious that Windows tablets are going to struggle to compete on price.
In fact, VR-Zone also reports that those same OEMs have suggested that, at launch, Windows RT tablets will probably go for £350-520, with some high-end products reaching £650. For reference, the most expensive WiFi iPad is £560. All told, these rumoured Windows tablet prices seem just a little bit too high to sell well. Let's wait and see. [VR-Zone]
