That's not exactly true. You guys have to remember that the Celeron M = Pentium M minus 1MB L2 Cache & SpeedStep. What does that mean exactly? Well having only 1MB L2 Cache (vs. 2MB for the Pentium M) drops the performance by ~5-10%...not that big of a deal, and nothing you'll notice during everyday tasks. Having no SpeedStep means the Celeron cannot "throttle down" its clockspeed when you aren't doing CPU intensive tasks. That lowers battery life by as much as ~20%. But the Celeron M is still a Pentium M at its core, and thus it is noticeably better than a Sempron in gaming and many CPU-intensive tasks. The Sempron has a paltry 256k L2 cache (one-fourth of the Celeron M) and it wasn't designed from the ground-up to be a mobile processor, meaning its battery life will be lower than a comparable Celeron M laptop. The XPRESS 200M should provide slightly better graphics performance, and another plus of the HP is that it has no rebates. Right now the Toshiba from CompUSA does have a rebate (although I haven't seen an ad scan confirming any other details). EDIT: Although I have to mention that CompUSA has done a fantastic turn-around of their rebate program this year. During the Compaq-CTO desktop fiasco, I got my $300 CompUSA rebate in four weeks.
