How long before the Nook gets a redesign and a new Windows 8 OS? This is a good move for both Microsoft and Barns and Noble, in my opinion. The Nook reads ePub files – which makes this publisher smile – and does it well. Also, Microsoft ditched their proprietary .lit format and their Reader software a while ago, but they don’t want to loose the eBook market. It only makes sense that Microsoft would pick up the Nook, which has a following and a retailer behind it.
