Microsoft and Intel have been sucking all the profits out of the PC market for the last 10+ years. The PC makers are operating on razor thing margins and have little budget to innovate. When they do innovate they have no ability to update the software as required, depending on Microsoft. Microsoft seems content to ride out the Windows monopoly on the desktop. Apple seems to be doing slightly more, but their focus is no longer the desktop either. I don't see any killer apps coming that is going to push the desktop to the next level.
