I have a MBP 13" without a touch bar. I've had it about 6 weeks. So far some of the keys have been a little sticky when cold. I had it in my semi truck at work and it would get cold, but after a few presses they were fine. The only real problem I've had with the keys is the space bar. The right side which I use predominantly got mushy and didn't click on the right, but it would still work. Just had to push it a little harder, but it also worked it self out. Though the right side of the space bar does sit a little bit lower than the left.
The only other thing that has happened is the computer crashed twice and had to reboot. But I was installing a lot of software when I first got it so I think I just didn't reboot it afterward and that was probably the cause. The battery has been perfect. I don't work it hard much. I haven't really gotten into video editing or music yet(which is what I bought if for along with the battery life). But I get probably 9-10hrs out of it. It's usually about 2 days before it gets to 20% or lower. I don't have a problem with it not having a mag safe plug as it only takes 2hrs to fully charge the battery and I just put it some where that doesn't leave the cable vulnerable to a snag. (also I don't have kids) Everything else, usb-c ports (I can't wait till a thunderbolt 3 flash stick becomes available to take advantage of the 40gbs data transfer), headphone jack, speakers, touch pad, screen, hinge, and wifi (I've never seen so many wireless connections come up on a wifi device) all seem to be in flawless working order.
This is my first macbook, so it was a bit disheartening to have issue with the space bar but it was good to see someone on here had apple request to keep they're defective laptop to investigate and correct the issues with the keyboard. So if I do have to have to keyboard replaced before the warranty is up it will likely be an improved version with the kinks worked out. I really like the keyboard. My older laptop has never had an issue with it's keyboard but it is a very mushy keyboard.
The only thing I think I could say was lame was to get rid of the SD card slot, and I think the touch bar is a waste. 3-400 extra for a bar that just puts an image under your fingers for what you would other wise use the touch pad for or a physical button. They should have just ran a mock ad that had a person looking at it and then showed them try to touch the screen and a hand pops up or the touch bar slaps there hand away.
Apple just needs to suck it up and make a touch screen if they want to remain relevant, or since they have such large track pads, make that compatible with the apple pencil or put a screen behind that. I don't like cleaning up a screen to remove finger prints and the touch pad could be like the gorilla glass. Stupid touch bar. The only thing relevant is the touch id, no need to enter passwords, confirm payment with it, multiple user login at the touch of a button. That is a nice feature. I feel sorry for those who bought that version, smaller battery, and so many issues. And I've heard no one who reviewed it yet that has said it really made anything but a distraction as they had to look at it rather than the screen when working with it.
