This is not even a little normal. I've seen previous rounds of complaints, I've had complaints before, but this is a totally different ballpark from normal.
There's always "a lot of pro and con". What I've never seen before is a significant number of returns. Like, yeah, I bought 2011 and 2012 machines when the rMBP came out, because I hate glossy screens, but I could basically live with the machines, since I mostly work in clamshell. (If I were working with the laptop almost-always as a laptop, I would have had to quit Apple sooner.) But this? No. This is not normal.
For cryin' out loud, no actual shipping product exists which lets you do the "just one cable handles everything" that is the big selling point of USB-C, because the MBP needs 85W and nothing does that except Apple's charger and the fancy new LG monitors, and the LG monitors don't have any of the ports people are looking for without dongles. There are rumors that an actual product could fill that need sometime next year. Maybe.
In the last 30ish years of owning Apple products, I returned a Performa to upgrade to a higher-end Mac. Until now. Of the three 2016 MBPs I originally planned to have for myself and my spouse, we ended up with two 2015 MBPs and a Dell. That's a Vote Of No Confidence.
