Microsoft Patents A Modular PC With Stackable Components (venturebeat.com)
Microsoft has patented a "modular computing device" that would enable people to put together the exact PC components they want, allowing for replacement of certain parts rather than forcing people to buy entire new computers when they want upgrades. Microsoft applied for the patent in July 2015, and it was published earlier this week, on February 11.
Really, Project Ara + a practitioner skilled in the field should == invalid patent.
For the the US patent office, they will likely assign someone who has never used a computer before, and will believe MS has described some kind of magic machine.
