So... my girlfriend... New Unibody Macbook 2.4... the trackpad wasn't responding well. You'd click it and there would be no response. You'd have to click extra hard just to click whatever you're trying to click on. Laptop is well over a month old... maybe 6 weeks. There is no Applecare on it yet... She took it to the store...they looked at it...and then... "Oh since you just got it, instead of us repairing it, we'll just give you a brand new one." Bravo Apple.
