Agreed the article is pointless. They basically say stick with your current version of Windows, switch to Linux or switch to Mac or go totally crazy and switch to "the cloud" (Chromebook) or buy a tablet. Wow genius needed to write this article!
This kind of stuff is always published on Sundays. The good journalism has to wait for weekdays: when office traffic, the news room being fully staffed, and new news to write about all intersect.
I found the article very skippable because it really shrinks down to what you stated in those two lines, a prejudice cruzade against a plat. Zdnet at its "best".
