All I can say is don't let a single person steer you away from either of the laptops... As speedy said, some companies have lemons... It also really depends on the user. I hear of so many people who complain about the Averatec 3270(what I own). However, it's truely been a great laptop for me. Some people complained they got less than an hour of battery out of it, and here I still get over two!
As for your question... Eh, if I HAD to pick between those two, I'd probably go with the Dell... However, I've not taken the time to research either like I normally would. Check around, find what others say... See how many posts you can find regarding those laptops. Which posts are problematic, and which are praising it.
