"I don't think you could build a tablet PC in that form factor with even a low-powered Centrino," Brookwood said. Laptops like Fujitsu products, with Atom, could cut into shipments of the lower-end processors, but the laptop is new and results have yet to be seen, Brookwood said.
Atom might bite into sales of Celerons first, followed by Pentium dual-core chips, which are on the lower end, said Dean McCarron, principal analyst at Mercury Research. With expenditure in check, people may instead opt for Atom-based systems.
"So far, there is not a lot of evidence that has happened, but it is certainly an area of concern," McCarron said.
The use of the Atom processor is evolving, said Bill Calder, an Intel spokesman.
"What you're seeing is an evolution of the category. We've seen some areas where [PC makers] have expanded and broadened the feature set," Calder said.
