Of course I didn't return mine. I knew what I was buying, as a long time Mac user I was not surprised that you could buy a gaming laptop for half the money. Also, I am not antagonistic towards change. If Apple makes a new keyboard, or a new trackpad - I am trying to observe it as a part of a larger whole, try to understand the decision behind it and see if it fits into my workflow.
People saying the trackpad is too large obviously only use it to copy files or surf the web. They don't use it for Photoshop gestures or to precisely select parts of the image without the mouse, they don't use it with custom gestures with BTT, they don't appreciate it's benefits, they only see the downsides because the cursor, perhaps, sometimes moves a bit while they type. So they say things like "it's too large". You know what, a DSLR camera is "too large" as well. So is a Wacom tablet, so are professional headphones.
I am also ready to adapt to new designs. A keyboard is a keyboard - I can blind type on an iPad, I can type fast on a mechanical keyboard, I can thumb-type multiple pages on my iPhone if the need arises - I adapt knowing that every tech has it's benefits and downsides. I do not type for an hour and decide I hate something that was designed by cutting edge design teams because I'm used to something else. I try to make it work, because I know there is a reason behind every decision. And then - I start to appreciate what the designers did. Some people learn how to type without hands. It seems some can't type if the key travel is 0.5mm shorter. I like the new keyboard, it screams high quality.
I also don't expect every new technology to become instantly usable, especially on a pro product. You need to learn to use your tools. I am not a teenager using my phone for Snapchat. At first, I didn't know how to use a Touch Bar. Then I used it occasionally. Now I use it in Photoshop every time I work, because I understand what it's good at and what it's not. Could I use a computer without it - yes. Am I glad it's there? Oh yes. It's great. Saves me time and, heck, even makes things a bit more fun.
Also, I knew it came with 16Gb RAM. If someone returns theirs because of that - it's just silly. It's not like you discovered it had 16Gb RAM while using it. I knew how much I needed. I know how RAM works, and I know my workflow. Also, I don't buy RAM to put it in my signature, nor do I open a few browser tabs, see that 10Gb RAM is filled and deduce that I need more than 16 because websites became somehow bigger in the past two years. I know how system manages RAM. People who knew they needed more, they didn't buy this computer, end of story.
Finally, I knew it was expensive. I payed good money for it. That money equals lots of hard work. Still, I did not expect to get a gaming console, a rendering farm and an ultraportable tablet in the same machine just because I payed a lot. I expected a great MacBook Pro powerful, portable, quad-core laptop - I got one.
