Fortunately, the computer worked and worked well from the start for me. The performance is phenomenal, the craftsmanship and style are only slightly short of amazing. (sturdy and stylish, but heavy and heats up quickly.) I hope I never have to deal with customer service but the product performs. The worse thing is that if you have it set to use full power all of the time you get maybe an hour and a half of battery time. Still like my PowerBook better though.
