i wish my brand new state of the art high school did that, i mean $78.8 million would be enough to buy 1900 students laptops, but they didnt. What they did do is give each student 100mbs allocated network space for saving homework on at school.
The centrino cpus range from 1.5 to 2 mb level 2 caches, i believe thats the big diff and why they are so expensive, i mean like the pentium 4 extreame edition desktop cpus cost $900+ that has a 2mb level 3 cache. And centinos are low voltage, small, and the computers have something special wireless thing built in, i'm not sure what it is. I know there is 802.11a b and g wireless, i'm not sure if centrino is anything diffrent. Most laptops now have 802.11b and/or g, but centrino i think has something different about it

Centrino is not really a thing, it's more of a specification. Kind of like a certification. To be certified as "Centrino" you have to have the following:
A Pentium Mobile Processor which is capable of using intel's speedstep technology.
A mini-pci wireless card which can regulate it's own power consumption to save battery.
Intels speedstep technology allows you to underclock your processor on the fly to conserve battery. I can get my 1.5 ghz processor to operate at something like 315 mhz when I don't need it. It's pretty slick.

thats the diff, wow, nice, thats how the battery life lasts so long but sacrifices performance. Cool, i learned something.
Thats awesome, I want centrino. Does it come with software to do it? Or is it like changing the size of your page file? (That kind of menu) That would be sweet, because I don't need that much power all the time..often its just email/internet I need.[b said:
Centrino technology automatically regulates cpu clock speed in windows, you can't "lock in" to certain frequencies as far as I know in windows. Though it's possible that there is software that will keep you clocked down. I think windows does a pretty good job of regulating clock speed anyway.
