No. Only some parts of the article address mobility. The article is about Windows 8.1 Features not, specific devices. The other part or basis of your comment is wrong. Windows 8 was & is designed to work across multiple/all devices (NOT specifically tablets, notebooks et al). Windows 8 is equally 'at home' on a non-Touch PC as it is on any other device.
