Well, there are technical differences such as bus speeds and onboard cache size, but the average user won't know beans about that. The Celeron is basically a stripped down Pentium III processor. And the P4 is the next generation after the P3. Truthfully, I've stopped following all the details of the Intel processors because they're all so darned fast the it doesn't really matter anymore. Please see my post above regarding all the stuff I run on a Celeron 466 laptop. Unless you're doing digital video, heavy duty computer programming, or serious gaming, even the lowest of the low end of the current laptops will be fine for today's applications. For the best value, I would look to the Celeron. P3 is old technology that vendors are trying to get rid of, and will probably not have the battery life that a P4 will. They added some power management features to the P4 that make it go quite a bit longer on a battery charge.

You could get caught up in so much technical mumbo-jumbo, but what it boils down to is this: If you don't already know the difference in processors, then any of them are fine.
