OK I'm leaning towards the HP.
Recently I have heard reports of i7 laptops getting really hot. Is that true?
Also in response to WR2, I mostly use Lightroom, Photoshop, and Vegas Pro (plan to switch to Adobe)
dont know if its just i7s in particular, however, im currently on a 17 in HP that is 7 years old, and at the one year mark, i had to have the monitor replaced because of over heating. the heat from the cpu cracked the monitor frame. hp was aware of the problem, and fix my for free, even out of warranty.
no problems since.
im also shopping for a new laptop, and it is a must for me to have a 17 in +, and have two hard drive bays. my current dv9040us has a 64gb SSD in bay 1 and a 1gb WD in bay 2
some of the dell 17 inchers also have dual hdds
i own a 14in acer also, and i have never had problems with acer products
