It would save more time and avoid the appearance of impropriety if they declared their Microsoft sponsorship in the second paragraph, rather than after the article.

Edit: if it's unclear, this is not accusing anyone of bias: good writing should make any involvement in the subject matter explicit. See http://en.m.wikipedia.org/wiki/Appearance_of_impropriety The article is sponsored by modern.ie which is a Microsoft initative. I happen to agree with the article, however being forthright about these matters would strengthen its point.
