Usually, equipment that is all original from manufacturer will be ok for long usage. Those that have issues like burnouts, failures etc if one really look at the equipment in question usually other 3rd party stuff are being used. So long as the equipment is not a modded one, there shouldn't be any issues. Inferior accessories such as power cords, cables, adapters, these items may be well designed but are they perfect partners with your equipment? Also the work environment do play a part. Ample room for notebook to breath, dry conditions also plays a part in its well being.
FYI, this is my first mac, previous are all PC based notebook. All I can say is that the quality of finish is very high compared to other brand notebooks. So if it is quality finished, then it should be quality designed. I am enjoying my rMBP very much.

I have switched on my MBP since year 2012 till now, I only put it to sleep when I am moving my MBP to another place to work, otherwise it is running 24/7
Thank you for your feedback

I'm just bought my MBPr in May 2014, so since then I'm rarely shut down my macbook, only when going to sleep. After hear all from your feedback, I'm relieve now, means that macbook can turn on for long time. Btw, I'm using my macbook just for academic purpose (etc: research article, pdf, surfing, words), no multimedia/gaming usage
