content: Yep, spot on.  Unless you are a gamer, you probably haven't needed to upgrade your desktop computer since about 2009.  Maybe earlier if your machine was younger than Vista but could still run Win 7 well.  Investing in mobile was much more profitable - now mobile has pretty much reached the same situation.  (I have a Samsung Galaxy Note II, but after using 3, 4, and 5, I can't say that they are noticeably more responsive - only the camera behaves differently, really.) I believe this year we'll see a refresh of desktop chips, DDR4 RAM should be out, new 3D libraries (vulkan + dx12), 4x faster SSDs, and brand new graphics chips. Should be a good year.
