He also noted that Microsoft is beginning to adopt a strategy familiar to open source vendors: give away the software, and then sell support and related products.
well I happen to work in a Microsoft "ecosystem" and this is not what I see. What Microsoft is doing is a move toward the freemium model that is so popular with everything mobile and non-x86. Freeware instead of licenses and ad hoc purchases of "Support" don't pay the rent, there's plenty of evidence for that in Linux-based software that never goes from "project" to "product"...

If Windows with Bing is a sign of things to come is that there will be a subscription based offering for people who don't get Windows with a new PC. I'd be interested in seeing this go ahead, at the very least to see what's so difficult about getting Windows (and x86 Firefox) on my £99 Hudl2 tablet.
