1.) Beware Best Buy's tactics to get you to purchase accessories, maintenance services, and other things you do not need. (Best Buy has been at the center of many lawsuits over price adjustments and supposedly mandatory purchases.)
2.) Even if a minor problem arises during the first 90 days, return it. After 90 days it's entirely your responsibility, and minor problems in the beginning often foretell later failures.
Best Buy has an Asus UL50AGRF-RBBBK01 thin and light laptop that I like for $549 refurbished with a 90-day parts and labor warranty. New, it is $729. Do you think it is alright to buy a refurbished laptop with only a 90-day warranty? (Best Buy does not offer an extended warranty on the refurb.) I know that Apple offers the same warranties for refurbished as new, Apple is just a bit too expensive for me now. And, I am skeptical of Best Buy's business practices...but the price is right.
Thank you very much for any advice!
