If, like me, you prefer to keep your software up to date, then upgrading to Windows 8.1 seems like the next logical step, as everything moving forward will become exclusively compatible with Windows 8.1 and eventually Windows 10. If you've already invested in the Windows ecosystem – through Windows Phone, for example – then Windows 8.1 will make a lot of sense, both aesthetically and functionally, as the two sync well and the user experience is almost identical, bar desktop apps.
