It's no secret that the newest edition of Microsoft's operating system hasn't set the world on fire. But there are still a number of vendors that have made commitments to Windows 8. For example, Lenovo introduced new Ultrabooks and a "table PC" based on Windows 8, while other vendors such as Acer and Samsung are also expected to have a few Windows 8-based products up their sleeves. But just how many Windows 8 devices will there be on the show floor this year? CES 2013 should be a good barometer for Microsoft's new operating system.
