The 2.5" HDs still spin at between 3,600 and 4,900 RPMS, significantly lower than desktop EIDE and SCSI, and have less throughput because of the size of the platters. The bus is slower, because you have to compromise for good battery life, CPU reliability, so it doesn't get too hot to warp the plastic, etc. As I might have mentioned earlier, you should have a specific reason to get a notebook, like size (if you have almost no desk), portability, weight when travelling, etc. No one buys a notebook because it's a speed demon.
