Microsoft's Surface 3 has been on the market for over a year with no successor in sight, but it now looks like the lower-cost Windows tablet is on its way out... well, eventually. The company has confirmed to ZDNet that it will stop producing the Surface 3 by the end of December, or more than a year and a half after it hit store shelves. As it stands, the company says that stock is "limited." You might not get the model you want at your preferred store, then.
