A funny thing happened right around the time Microsoft launched its 10-inch Surface slates. Consumers decided they really, really like smaller slates, which cost less, are easier to carry and hold, and do pretty much their same thing as their larger sibs. Apple's 7.9-inch iPad mini is a bona fide hit, and the 7-inch Google Nexus 7 and Amazon Kindle Fire have found receptive audiences too. For Microsoft's mobile strategy to work, it badly needs a 7- or 8-inch Surface in the game. Not surprisingly, Redmond is planning to launch a smaller slate later this year, The Wall Street Journal reports. If true, would Surface's optional Type Cover and Touch Cover keyboards shrink as well?
