From the Android/iOS section: "Weaknesses: Not considered productivity tools by most, limited to app store software"
Then why do I see the vast majority of management types dumping their laptops in favour of an iPad? Not having one myself, I can't comment on the apps/functionality there, but it must exist.
Likewise on the Android front; I use my Transformer for practically everything at work!
I also know of no such restriction with regard to app store software, as I've installed apps from Google Play, Amazon, a handful of other stores, and also apps that I have downloaded from web sites & fora.
Sorry chaps, I like CNET, but I can't take this article seriously.
