Yep. After a bunch of quarters where consumers were spending money on small cheap computers, the people in ivory towers have discovered that the emperor has no clothes. M$ now operates in a niche of business and consumer notebooks/desktops which is not growing much. Hint: Without growth, M$’s business model falls down. The slaves are only happy to slave on if they get some crumbs. Without growth, M$ is the only one to get any crumbs and the slaves become resentful. Equate slaves with OEMs, ISVs, retailers, and consumers. Businesses are becoming disillusioned as more businesses, governments, educational institutions switch to FLOSS and GNU/Linux. Want IT for less in order to compete? Run away from M$. I suggest Debian GNU/Linux. It works for you and not for M$.
