Why does this model only come with a 5400rpm hardrive, I mean its a nice laptop feature rich and everything but I know it can't have anything to do with the battery I mean max it has to be around 2.5hr so why not add it? My guess would be just the parts at the time while they were making it. But this looks like a great machine the first to have an HD-dvd drive to my knowledge and 200GB of memory is still quite a lot.
