Being able to touch, click and press your way around an operating system with a variety of hardware configurations, while not alienating potential upgraders, is no mean feat. That said, Microsoft thinks it might have the solution. By introducing a new mode, a 20 pixel buffer will be designated to working with those edge swipes we've heard about. It'll also go towards preventing accidental hits around the, typically less sensitive, edges of older screens. It does mean that you'll be losing a little real estate, but perhaps a small trade-off for being able to keep your Windows 7 touchscreen device. Going forward, Microsoft will be working with hardware providers to ensure new gear really shows off the new features of Win 8, but for now, legacy users can look forward to a better experience.
