I've got 2 laptops, and am going to give one to my brother. Both identical, but one has a celeron 2.8mhz w/128 L2, the other is a "mobile" celeron 2.4mhz w/256 L2. Has anyone done any performance (ha, ha!) comparisons on these two chips? I know they're both celerons but I'm thinking the 2.4mhz with the larger L2 is going to beat the 2.8mhz. Which one would you keep?
