  • It looks like Amazon’s 10-inch tablet will only ship in 2012, with a smaller, 7-inch model shipping in the fall.
  • It looks like HP wants to spin off its PC business, instead of selling it to someone else.
  • Yelp is scaling down its Groupon-killer. It seems a lot of daily deals offerings are shutting down or scaling down, which means Groupon is probably doing something right.
