much of a difference?

is the difference between the n270 and n280 processors that pronounced or is it pretty negligible?

im still really stuck on which to get.

Intel debuts new Atom N280, GN40 chipset - Ars Technica

the N280 is unlikely to offer any performance advantage over the N270—the chip is just 67MHz faster (1667MHz vs. 1600MHz). The CPU's bus speed has increased significantly, however, rising to 667MHz from the 533MHz FSB on the original Diamondville part.
......
The N280 improves significantly on N270's already excellent power consumption, with a rated TDP of 2W, down 20 percent from the N270's 2.5W. How much improvement this will make in real-world battery tests is still unknown; CPU power draw definitely accounts for a significant percentage of a netbook's power consumption, but it is far from the only factor.

Slightly faster. But not much. Improved power consumption too.
However nothing that is really making me run out to the shop and buy another netbook.
