As far as I go, I was a huge computer dork way back in high school, but I haven't kept up with anything, so I don't know what's good and bad out of anything recent (last 5 years). But here's my question: I'm looking into buying a notebook. I have a general idea of what I want as far as specs go, but what's the difference between all these models floating around? Example: Toshiba Satellites. I'm looking at their site, the P30 and P35, for example. The specs are different, but I can customize a P30 to match the P35. So if I do that, NOW what's the difference? P30 costs more this way. Same goes with the other Satellite models, M35, M45, etc. If I customized all the Toshiba Satellites (all 6 or 7 of them) to have identical processors/RAM/HD/video/etc. what would be the difference? None of them would be the same price. Thanks for any info, I'm quite confused. And this is after looking at just one line of one brand!
