Celeron M is not netburst its banias and Dothon based and gives A64 notebooks a run for thier money, not to mention much better battery life. To this lay person it looks like A64 notebooks are competing with celeron M as they seem to be in the same price range, with A64 slightly more expensive, but Pentium M seems to be going into the high end notebooks. As for Athalon XP M , celeron M is the better CPU IMHO.
