I've had almost every Apple laptop ever. I also collect Apple portables. I have Pismos, iBook Clamshells, etc. I bought this new MacBook Pro 15" 2017 about 4 months ago. While there are some things I like, there are several things that are significant issues for me: The keyboard. It's terrible. I make more mistakes with it than any other keyboard I can think of. The travel just isn't quite enough. The battery. Wow, did battery life ever fall off of a cliff! It seemed like my 2013 Retina MacBook Pro 15" had better battery life than this and that is comparing it in such a way where the 2013 MBP had 2.5 years of use on it! I know they reduced the battery size in this. The battery is not strong enough: I never get even close to 8 hours of use, or even 6. Maybe 5 hours. I'm not running really heavy duty Apps either. I can use it on and off for an 8 hour day, but actually using this thing constantly I seem to get around 5 hours. The TouchBar. I hate it. I find it all but useless. Just adjusting the volume or screen resolution takes more work than with physical buttons. When in Apps, why do I want to look away from the screen and down on the keyboard to input functions on some low resolution keyboard button bar? Sometimes this can be ok, but most of the time, it's just inferior to using on screen user interface functions. And how many times have I accidentally hit the Siri button on the top right of the keyboard! Lots. The trackpad. Man, is this thing unnecessarily big! I get spurious inputs sometimes because my palms will brush up against the sides of the trackpad, etc. And, just resting my palms and typing, I can feel the trackpad line where it starts on my palms. The trackpad needs to be slightly smaller. And does anyone think that the trackpad isn't as reliable as previous generation MacBook Pros? Many times I will do something on the trackpad, like try and scroll a Webpage with two fingers, and the first swipe isn't recognized. Then I have to do it again. I also find just moving the mouse pointer is not always reliable: I start to move my finger and there can be a slight delay before it starts moving. And then when slowing down, it's like it can miss a bit of the slowing down swipe, so the arrow doesn't always move smoothly throughout a mouse arrow swipe move. It's like it's not as sensitive or something, and it's annoying beyond words. Performance. I find that moving windows, typing text into Safari's URL field, and some other things can be jittery on this 2017 MacBook Pro.
