..Regardless of which laptop you choose, I strongly suggest purchasing a warranty with it. Best Buy has a really good one - when your laptop battery wears out, you can just come into the store and they'll replace the battery for free. It covers far more, obviously Hope this helps!
I strongly recommend against getting a laptop at Best Buy precisely because of their warranty. It sounds good, though expensive, at the outset, but I can tell you from personal experience it's very inferior to the warranties you can purchase from Dell, Gateway, etc.
I bought a Compaq laptop at Best Buy for $1100+ and then purchased their extended three year warranty for a whopping $270 extra. A few months later the power input connection on the back became loose causing my laptop to switch back and forth from AC to battery power, so I took the laptop into the store. Guess what, during the first year, because there is a one-year manufacturer's warranty, they ship the laptop to the manufacturer rather than working on it at their shop. What's worse is they wait until they have a few and ship them slow mail. They told me THREE WEEKS TO GET IT BACK. I told them I couldn't wait that long and would have to take it elsewhere to get it fixed, to which they replied THAT WOULD VOID MY WARRANTY.
Well, I really couldn't wait that long, so I stopped by an electronics shop and the salesguy there suggested I call Compaq directly. Guess what, Compaq paid for overnight UPS to and from their service center--I got my laptop back fixed in 4 days! Why didn't Best Buy mention this option? Losers. (The guy at Best Buy had kept referring to me as "chief.")
A year later, after the one year manufacturer's warranty had expired, lightning struck my Florida home and the laptop was fried. I brought it in for repair or replacement at Best Buy (their warranty covers electrical damage). Weeks later the store says my laptop is back from their service center (another area of the state)..guess what? They said the damage was not covered by the warranty because it was abuse. Further, they said that the service center notes show that they called me, told me, and that I declined to pay the $800 for repairs. Nobody had called me. They just flat out lied at the service center.
I asked them how it was abuse? They said the service center notes said "excessive voltage." Ugh! I said, of course..lightning..duh! Since lightning strikes were covered under the warranty I spoke with a manager back and forth over the course of a week and he sent the laptop back out to their service center where they kept it another week before labeling "dead."
Finally I was given store credit for the depreciated value of my laptop (899.99) and was allowed to apply that toward the purchase of a replacement.
Get a Dell or Gateway, etc., with an on-site warranty. Someone comes out to fix your machine a day or two after you report the problem. No questions asked. Batteries may not be covered, but I consider that a small matter compared to being without your laptop for a month under the Best Buy warranty.
