With the Classmate, they were successful in curbing the enthusiasm of the OLPC project (which faltered for many other reasons as well). Intel may have similar goals here, namely take away momentum from their competition, without actually having to sell many units. The Raspberry Pi has many uses, but one big one is a lightweight web-browser PC. That has the potential to cannibalize the traditional desktop market, which surely has higher margins for Intel. So their goal is to kill the low-margin market, not compete in it. If they announce a product that costs less than $100 and can run Windows, that may slow down Raspberry Pi from gaining traction as a lightweight desktop replacement.
