According to Microsoft's 10-K filing: "Surface revenue was $853 million". So the revenue for both Surface RT and Surface Pro was less than the $900M write down of RT. Wow, that's pretty embarrassing. I still don't get why Microsoft needs to be in the PC hardware business (besides accessories). They can blame OEM's all they want but really Microsoft's woes in the tablet space can be laid squarely at the feet of Bill Gates and Steve Ballmer. Microsoft getting in to the hardware business isn't the solution IMO. Unless they did so because they're worried about OEM's ditching them for Google?
