With the Core 2 TDPs, you could put a ton (well...many) Atoms, in one little CPU thingie (forgot the word)...maybe that will be Core 3? :P
anyways, Atom is really interesting.
cheers

Atom processors are soldered onto the motherboard, in other words: No, DON'T expect an easy upgrade from a single core Atom to a dual core Atom.

Atom seems very interesting to me. With 1,6GHz it's powerful enough for common desktop applications. Flash videos (Youtube), mapsurfing (Google Earth) and office products (OpenOffice) are good to go. With that it suits many family's needs if there are no grownups demanding better gaming experience (like me a while ago :P). Very tough competitor for AMD's BE models (45W).

With only 16W power output means little heat which means less cooling which means less noise which equals good. Maybe in a couple of years I might by one (or the successor).
