And I think the main focus of this drive is USB enclosures, so the rotational speed really doesn't matter as USB bottlenecks even 4200RPM drives...
I replaced my 5400 RPM laptop drive with a 7200RPM and noticed quite a difference in bootup and program starting times with very little change in my battery life (actually unnoticable unless I run defrag until the battery dies and compare the two). I'd make the recommendation to anyone on the fence to get the faster drive for a laptop.
