Intel is again starting to sell an idea to the market that many enthusiasts have known for a long time: Mobile CPUs in desktops has many, many advantages. This has been done for servers before, but never for desktops (from a marketing standpoint), and will most likely impact embedded or specialty systems such as small form factor boxes the most.
While it's doubtful that Intel will migrate desktop and mobile sockets into a unified one, the endorsement of Intel is completely novel and will probably facilitate an overall acceptance of low-power being better. With the release of cores like Conroe and Woodcrest, Intel is finally getting with the program and realizing that a CPU that uses more power than a 100W lightbulb has drawbacks!
