Dual Atom, according to a very high profile Intel executive is not meant for netbook and it should never end up there.

Shmuel (Mooly) Eden the Vice President General Manager, Mobile Platforms Group at Intel, believes that dual Atoms are too hot for netbooks, and that OEMs wouldn’t want to use something like that in their designs.

You need to put fan on a dual Atom, and this is not a very popular decision among netbook manufacturers. At the same time, the dual-core Atom is not really a power saving CPU, as it was not developed with mobile in mind. The power stats are not great and the dual-core will suck the battery dry much faster.

This is an indication that dual-core Atom in netbooks might not happen, even in the future. Intel meant Atom for the power conscious market and not for powerful computing. The message is simple, if you want more power than an Atom and more multitiasking, then you have to go for Core 2,

The Atom refresh, whenever it comes out, is still a single core.
