An eagle-eyed Verge reader has spotted a little bit of self-referential humor in Microsoft's choice of Type Cover 2 colors. A Windows Phone advert from October last year included a tip from Bill Gates to Steve Ballmer, with the original CEO urging the present one to "consider making purple typecover for Surface." Lo and behold, yesterday's announcement of the second-generation Surface tablets was graced by new pink, cyan, and yes, purple Type Covers to go with the original black. It's nice to see such a warm gesture of appreciation to the company patriarch, and it shows that Microsoft is indeed heeding user feedback — even if it is one very special user.
