Also, I have a Thinkpad through work - my 2nd one. Had both for 3 years each with no problems at all with either. Cost more, but they seem very reliable.
I've been happy with my Dell even though the original HD died after 14 months. Things like that happen randomly and I don't believe the extended warranty has value. Drive replaces easily BTW.
I purchased this one right after Christmas: http://www.newegg.com/Product/Product.asp?Item=N82E16834149046
They were selling it for $899, though. If you like that one you can find a better price than $999. Even for $999, it has no competitors in the "best bang for your buck" category.
