well as per said by the link to the review,
in terms of performance there are not much difference.

The main difference that will be obviously noticable is the battery life, with a celeron m notebook you will notice battery shrinks much faster compared to a centrino notebook, that's it.

The other one is the cache, which will only be noticable when you have a lot of memory hungry programs opening simultenously.

Other than that, celeron m is as good as pentium m. Those replies that said celeron is a much 'slower' (obviously you are implying speed) processor didn't get the facts right.

yeah, simply trapped into intel strategy. lol

So does anyone know the range and prices of IBM celeron - M notebooks?
