So I took it in, told the genius(hate to have to call an idiot a genius...) the story and waited for his response. This was the slowest guy I've ever encountered so I waited for a long time for him to tell me that they'd have to repair it again. Just to check what my options were, I asked if I could return it and get a replacement. He said that it 'might be difficult because it had been repaired already', but then said that if I took it to a manager, most likely they would not check if it had been repaired and just swap it out for me. So I had a choice.
It's too much of a gamble. I could have asked for a replacement, but there is a very considerable risk that something will be wrong with that one and that it would cause more problems than simply asking for a repair. I opted to give them a chance to repair it and if something else doesn't work at that point, I'll just take it to the manager and ask for another replacement. I do feel that Apple has no shame sometimes. This is a brand new computer! They should apologise to me and then bend over backwards to make it up to me somehow. Nothing though, barely an acknowledgement that this was an incovenience to me and, even worse, the guy made it sound like fixing the trackpad button was being 'picky' and that, by extension, all of this really was due to me being overly particular.
To be honest, I genuinely hate Apple for having such shoddy quality control and for forcing me to spend hours on the subway and days without my computer to sort out their crappy quality products that I paid several thousand dollars for. The only saving grace is that Apple service is pretty good - not that the guy this morning was good because he really was one of the most uncommunicative service persons I've come across. The suggestion that somehow because I've repaired the item I would not be entitled to the 14 day return period makes me angry - I doubt that they can legally get away with that unless it's stated somewhere, and I don't think it is.
In any case, I fired up my WONDERFUL Pismo and, like every time newer, fancier machines are at Apple for repair, Pismo starts up and works perfectly,carrying me through the hard times - everything is perfect on this computer, even if the display is no longer as bright as it once was and even if it is terribly underpowered by today's standards. It 'just works' - Apple at its very best.
Long live Pismo!
