Celeron is not a platform, its Intels low-end processor family as one of the other posters said, I think you are confusing it with centrino mobile technology. Intel has three main processor families in the consumer level (busniss is different completley). Celeron, Pentium, and Core. These three families break into more specific family branches. Go to www.intel.com and you will get all information about thier technology, products, and all that stuff. Its a great website.
