Windows 8 not helping
You're right, it's not *all* windows 8's fault for declining sales.
However, it sure isn't helping. Nobody (and I mean *nobody*) I've talked to has liked Win8 on the desktop.
I think the article draws an incorrect conclusion from BYOD. I don't believe that cost is the primary factor for a BYOD purchase. BYOD allows people to select the laptop (machine, whatever) that makes sense for *them*, not the cheapest one that a company can purchase in bulk.
It's an important distinction. While some will buy the cheapest laptop, most will buy the best they can afford. I know I did -- I went for a top of the line Macbook Pro. It's going to last me 5 years (as my last one did), and I want a system that will still be relevant after 5 years.
