I have purchased many, many electronic things in the past, and had never scrutinized a purchase as much as I'm doing this 15" PB. I feel paranoid about it, and possibly try to find defects where there are none. Are we Apple users that picky? I've owned other Apple products before including 2 iPods and an iMac and never been so thorough about them as much as this PowerBook. I hate reading junk posted on boards. I never knew about the horizontal lines - until I read about it here. Now I see them in my PB, and in my girlfriend's Dell laptop! I had never seen them there! Now I have a dead pixel and I think my optical drive makes a weird noise when I turn on the computer. It completely kills the feeling of happiness of any new product and creates an illusion that there's something wrong with whatever you just purchased. Why? Have you ever scrutinized any purchased this much? We'll never be happy about anything if we can't settle for what we've got.
