I call bull**** on the headline, and the article stinks of fabricated "facts".
On the other hand, Intel's NUC concept, which should be on shelves soon, should satisfy 80% of the market. A 17W chip is now more than able to run Excel, or VLC at 1080p, so there goes the DIY office PC and HTPC. The cheap SSDs that fit the NUC box are now big enough to handle any amount of archived emails and more than a few apps. Good riddance to building office PCs and the never ending fight to find quality, reliable components.
For everyone else, I don't see much changing. High end CPUs will always be available to pair with the MB of your choice. Any rumours to the contrary are probably bull****. There are just too many permutations to possibly pre-build systems for even 20% of that market. **** knows who started these rumours, or why.
