I've been to a service centre four times for my one MBP in 2 years. Logic board, keyboard, SD card reader, Super drive and power brick replacement in warranty and battery replacement out of warranty. My battery died, it swelled bringing my trackpad up making it almost unusable, before it finished its 1000 cycles. I still payed the full price because it was not in warranty. But that's alright to some extent, it's just money. Did the fix my issue every time? Yes. Did they do it on time in every case? Yes. Did they act ethically and professionally, not overcharging or making unnecessary replacements? They most certainly did.
Why don't I still feel very good about it? For two reasons,
1. A new MBP comes in multiple times for different issues during its first year, there must be something wrong either with the device or with the way it was handled. Now, I am not the most protective about my devices as in I don't put on cases and covers for protection, but I not very careless about an expensive piece of machinery either, there were no physical damages, dropping or liquid spills. Now, in the feedback there's always a point for timeliness, information, etc. but there isn't any for warmth. Of course, that cannot be quantified but it still is necessary. I've worked for a call centre before dealing with the internet issues of UK folks and if I learned anything from that was that a friendly and warm attitude goes a long way in calming down people even when there's nothing you can do about something like an area wide internet outage. I am not saying the people I dealt with were rude or unprofessional, not at all.
But I didn't feel like they understood my problem and went "out of their way" to do something about it.
2. Apple. One does not need to go any far to learn how to provide a world class service. We read about it all the time in the news and may be that is why we have such high expectations from the service folks too. And until Apple manages to setup stores here, the third party ones have to find a way to not only emulate them in the best possible way but also to change and adapt a few practices to suit us Indians. We as consumers are quite different from those in the states.
One does not need a lot to do both these things. One just needs to look in the right direction with the right attitude. Kudos to those who service people well but keep in mind there's always room for improvement. And I always believe in "will over skill" that's why I think it won't be difficult to do if someone really wants to do it.
