It's not wrong that this was probably one of the best hardware designs and Apple was wrong not to just keep upgrading the processors and memory and churning machines out... but since Apple decided Touchbars and shitty keyboards all for want of a few millimeters that nobody cares about is the way of the future, we're stuck looking elsewhere for hardware.
I have to personally admit that I have seriously contemplated buying one of these 2015 machines refurbed, as my 2012 MBP is on its last legs and I need to replace it... six months ago. I also looked at the machine in this article and really quite liked the hardware, but would never buy it from the company that's building it, which is another market fail.
(And it's also annoying to watch people call the machine in the article a Macbook clone, when it's really closer to being a Chromebook Pixel clone, all the way down to the 3:2 screen; I love the Chromebook Pixel too, but living with Chromebook hardware as a software dev is a high-level annoyance that I wouldn't wish on anyone for their daily driving experience.)
