It bulges down, only a little bit. Weight, you can check Dell's website.

Many people want i7 quad because they think its "power" will benefit them. I think the opportunity cost is battery life (if you're mobile often), heat, and power, as well as performance in normal use.

"wouldn't it be better in the long run to get a higher grade processor assuming that technology is advancing pretty fast" yeah that's what I thought but trust me the current Core i7 quads are not that advanced. Sure, they have turbo, but it only turbos to 2.53GHz etc for two or less cores, it can only work the four cores together at the base speed (very low, 1.6GHz or 1.73 GHz for 720/740QM).

Besides, if you think the current Core i7 quads will be able to last long, they actually were sold before these Core i5s. Apart from turbo, i5s are not that much of an improvement over Core 2 Duos with high clock (plus they have greater cache, lower TDP, etc).

If you ask me Intel is not "advancing" very well. Mostly we get i5 or i7 because they are new.

So are you sayin that i should chose the i5 over the i7???im really confused now...lolz... never knew it would b this complicated... so if it was you guys u would take the i5 rather then the i7??

Hei i read a few forums, some of the guys said the OPTIMUS technology only is for the i5 version and is not in the i7 version... is that true?
