I disagree. The 15" MBP is still pretty heavy and big to carry around. At half the thickness, and say 2/3 the weight, it would be a much more reasonable daily driver.
And i disagree with you? What you consider big and heavy i consider basically feather weight. Its light, has a great keyboard, decent battery and all the ports. it's perfect. i don't want it any lighter tbh.
Maybe there should be a 15" MBP lite that is just that?
While thin and light is nice for carrying the laptop around, you still want a laptop which offers everything you need to do your work. And the late 2015 MB Pro seems to be the smallest, which hasn't made painful sacrifices. It offers a reliable keyboard and a wide selection of ports. Having at least one HDMI port is very convenient. It also has a large battery. The only thing missing, and I would sacrifice further thinness for it, would be easier exchangeable battery and ssd storage.
It seems strange no one in this thread has mentioned thermal limitations of such a thin and light design. True current CPUs are more energy efficient than those in the past but you are still going to get throttled when the machine is working hard from what I have read.
Also as you said, user replaceable battery, ssd and ram.
Thermals are indeed a good reason too. While it seems that the current MB Pro does a reasonable job with cooling the CPU, it is obvious that with better cooling you could drive the CPU harder. As the laptop is for me a mobile workstation, there is also the point that I would prefer a slightly bigger laptop that runs faster.
Which is why Apple should differentiate between the "air" and the "pro" line more. There would be a place for a 15" air, which is a slightly thinned version of the current 15" pro, and a true pro machine which sacrifices a bit of portability for features and performance.
My current dream machine would be roughly like the late 2015 MB Pro (that happens to be the machine I am typing this on), with at least a 16" screen (the bezels are plenty large on mine) and 1-2mm more thickness, allowing for good thermals and more serviceable parts. For a pro machine a battery, keyboard or ssd exchange needs to be doable by a skilled technician on-site.
I have one and it’s great for daily use. I’d really like an upgraded 12” MacBook for traveling though. I mostly use a very old ChromeBook but there’s no real replacement for that available.
To me it seems an oddly missing niche. A lot of people spend a lot of time on planes, don’t need much of a laptop, and often don’t much care for tablets as laptop replacements. Nothing really on the market for them.
Are you serious right now? Half an inch thick and 4 pounds has a negative impact on your daily well being? For what I assume is a work computer. You've never picked up a shovel or any other tool in your life, have you?
