The new Windows 8 operating system signifies a big shift for Microsoft. Once released, it will transform the way that people use desktops and laptops with Windows. And the new operating system's touch screen format will undoubtedly be a major adjustment for any lifelong Windows users.

But this change may pose a problem for some users, according to PCWorld. After sitting in on a customer preview, the source reports that, although Microsoft states that devices running on Windows 7 will be able to use the new service, there are a few elements that may not function as well on older hardware.

Overall, the new touch screen set up was a bit unresponsive, occasionally requiring multiple taps and flicks to get the device on trial - an  HP TouchSmart 520 PC desktop - to take action. But, there were reportedly a few technical problems at the preview that could have contributed to the delays.

And while the touch screen format is the standard for tablets, and becoming increasingly so for notebooks and laptops, the publication states that "using touch on a 23-inch screen [desktop]" still feels a bit strange, "like conducting an orchestra." The source predicts that many users may ultimately choose the more familiar desktop mode, at least at first.

Another design aspect that hadn't been entirely perfected was the live corner function, which occasionally took users back to a past application or unwanted menu screen when all they wanted was to refresh their browser.

The greatest task ahead for Windows fans will simply be adapting to a very different user experience. But, the best way to prepare for the switch is to consult a retailer at PortableOne. They can determine the best option available to embrace the new system, whether that means buying custom upgrades for laptops, or purchasing new devices altogether.
