cbrunnem :
must not have ever met a college student, who in case you havent notice buy a lot of laptops. just today i had 10 plus tabs open while running media player while running MATLAB and inventor. i also had 2 excel sheets and a word document open with prolly a few folders open as well all just to complete one class's homework assignment. i use 3ds max to render out short clips in the background occasionally too. so just because you or others do not multi task like in the video doesnt mean others do not because i am in a similar situation as that video, occasionally.
Btw i have a i7 laptop so im not toooo biased
Of everything you're saying there, pretty much everything is low demand except inventor and 3dsmax. Media players, internet browsers, and even Matlab (most of the time) don't actually use much CPU power. That kind of multitasking, while extremely common, is much more dependent on quantity of RAM than it is on the quality of your processor. The situation in the OP is much less common, and it's certainly not something you'd do on a laptop with an IGP.
Oh, and for the record, I'm also a college student, and I'm currently running media player, folding, google earth, 12 tabs of firefox, matlab, thunderbird, word, excel, and I have half life 2 minimized. Why? Because I rarely bother to close things. At any given time, only a couple will be actively doing anything, so the rest are basically sitting there idle
