I think we have to rethink where we believe the next windows editions are headed. 4th quarter 2010, the mobile devices (Smartphones and Tablets) outsold the PCs for the first time (101 million versus 97 million Worldwide). So that's where the action is going.
In addition, the ARM (RISC) processor manufacturers came out with Duo Core processors and before year-end we will see Quad Cores. Qualcom is said to come out with a 2.5GHz Quad - that is more than e.g. the Q6600. That will make them eligible for netbooks and laptops. With their very low power consumption those devices will run forever on one charge - especially in combination with an SSD.
And what does that mean for Windows? I think the focus will shift from the traditional PC boxes to those new devices and their components. Already today you can run e.g. a Motorola Atrix Smartphone as a desktop and that is just the beginning. The traditional big desktop boxes may be a thing of the past except for some hard core enthusiasts that build one themselves.
So chances are that we will have to say goodbye to the ways we were doing things and learn a new world. But that it OK with me - a lot of exciting things ahead.
