I just got back my uMBP (Mid-2009) after the Optical drive failed (7 days without my uBaby!). To my surprise they had also "Replaced the Trackpad" (said the Genius) and described it as a 'Trackpad Assembly' on the Work Confirmation Sheet. I asked why... and he said the Trackpad had failed a diagnostic test (though I never had a problem with it!). Now, the trackpad's top left corner and top is raised *above* the body case to such an effect that I can actually place my nail under the trackpad. I am pretty angry that they replaced it without my consent and did a shoddy job as well... How unhappy should I really be? I still have AppleCare, but I don't want to wait another week without a computer... Suggestions?
