Simply put, the Lenovo Duet offers Microsoft Surface quality hardware and accessories at a fraction of the price.  Superb top-notch value.  However, ensure you are comfortable with using Chrome, or wish to become comfortable with using Chrome, rather than MS Windows.  Chrome is basically a glorified Internet browser as compared to Windows and, "synching," files between Chrome and Windows devices can be a bit tricky.  Overall, I have enjoyed using such a high-quality device to become more familiar with the refreshingly streamlined Chrome OS.
