Thanks to smartphones, most of us these days are familiar with the idea of a sliding mechanism underneath a display screen revealing a physical keyboard. So why has it taken so long for someone to take this idea and use it for a tablet computer? Thankfully, both ASUS and Samsung have now introduced this feature to their new tablets, albeit in slightly different forms. The Samsung PC7 series tablet runs on an Atom processor, benefits from solid state storage and has Windows 7 as its operating system. Its high definition, touchscreen display should also be capable of comfortably handling indoor and outdoor use thanks to its 340-nit brightness.
