I've had two experiences with "Geniuses" and repairs to my Optibay HDD replacement. The first time, I brought my MBP in due to freezing issues that stemmed from the logic board. He saw that I had replaced the optical drive and told me to put the drive back in and bring it in later because he can't work on it like that because it's technically against the warranty. Very customer friendly response, I really appreciated him looking out for me. I brought it in the next day and he fixed the computer right up for me. Extremely happy customer. The second time, I brought my MBP in due to a trackpad problem. I forgot to replace the optical drive before taking it in. The "Genius" for some reason had to run diagnostics on the machine and noticed it was missing and immediately started telling me my warranty is void and was generally just a jerk who wouldn't work with me. He even admitted that the optibay replacement had nothing to do with my trackpad issue yet still adamantly refused to do anything to help resolve my situation besides telling me that my warranty is void. Pretty terrible customer service considering I had bought a $2500 MBP and a $350 AppleCare warranty. I did end up replacing the drive and taking it to another Genius Bar, he didn't find the need to be a company man and run diagnostics on my computer for a trackpad issue. He just took it back, tightened a few screws on the trackpad and returned it right back to me 10 minutes later. Fantastic service. Anybody else have any issues or success with your optibay replacement and the Genius Bar?
