I have to agree, with reservations, to regedit's comment. The reservation is that I really do not believe Microsoft are that foresighted, or imaginative.
Like you, Trouble, I have chilldren and grandchildren (now all in their late teens). Three of the children are actually in the IT business. They rarely sit down with their mainstream computers. All their social computer interests are done, mainly, on their mobiles. Only four out of 13 of our family, including myself, have desktops, although the remainder do have advanced laptops and Ipads.
