I would never consider purchasing any O/S if it forces advertisements upon my face. I remember in the early 2000’s, BS like this was often referred to as adware, and was avoided by users everywhere. What happened to this mentality? Now, most of the “free” apps on the Android market come bundled with ads, and I can’t see any end in sight. Now this same crap is appearing on the desktop!
Everyone, for the sake of your own sanity, do not buy any O/S that uses such anti-user strategies, (unless you know how to hack these annoyances out). If that means switching to something that’s free/open sourced, that’s even better!
I do hope that ReactOS reaches beta status soon, heaven knows we need it.
