Microsoft’s first serious foray into tablets came just after the turn of the new millenium, with Bill Gates demonstrating the first tablet PC prototype onstage at Comdex in the autumn of 2000. From there, OEMs started releasing tablets based on Windows XP Tablet PC Edition in 2002, with a full range of pen-enabled slates and convertibles releasing over the next few years. In addition to oftentimes prohibitive cost, each had its own set of drawbacks. Convertibles tended to be quite bulky compared to their notebook counterparts (the ThinkPad X-series being a notable exception), while slates were rather difficult to use - a symptom of shoehorning a desktop operating system into a purely touch-centric form factor.

Fast forward a decade, to the beginning of 2010. After a number of conceptual non-starters in the tablet PC space - building tablet PC support into all editions of Windows Vista and 7 (other than Basic/Home Starter), the entire Origami class of devices - Microsoft’s touchscreen devices were floundering. The iPad had been announced to mixed reaction but an extremely high level of anticipation. Microsoft and HP countered with the Slate 500, an Atom-based device shown off at CES 2010 with solid state storage and Windows 7 in roughly the same form factor as Apple’s iPhone OS-based ARM tablet. With speculation pointing to a pricetag of just $549, the Slate appeared to be the most viable hope Microsoft had in trying to make mainstream headway with the tablet PC concept. But shortly after the iPad shipped in April 2010, rumors of the Slate’s demise started to circulate, and after a six month delay, the Slate 500 started shipping as an enterprise-only product in December of that year for $799. HP’s acquisition of Palm (RIP) definitely played a role in the sidelining of the Slate, but more importantly, it essentially spelled the end for the tablet PC. This was news that was perhaps known already, but the Slate saga officially pulled the plug on Microsoft’s original idea of what a tablet was.
