Dear Apple,
Most people, at some point, will not be starting their 15th consecutive hour of work on their laptops and will eventually go to sleep for the night or simply go outside for a walk, at which point they can recharge their laptops.
I remember how cool it was to replace a G3 iMac with something totally cool and new, like my 2009 iMac. It looked different, totally new product. Now, 8 years later, why should I bother getting a new iMac, it's basically looks like the same Black/Silver one I own now that also has macOS Sierra (which looks the same since like OS X Tiger, more or less) running on it.
Thank God all your products are Linux compatible for when I get "obsoleted".
