How so? It does not seem to have a single Thunderbolt 3 port. MBP has four of them. Instead, Xiaomi has a bunch of USB-whatever &c. That is not "better", that is strictly "worse" and cheaper.
Are you serious? Every single person has specs they care about and ones they don’t.
I don’t think the resolution is interesting at all, but I agree some will.
For some people the great MPB trackpad is enough to sell it. Some people want the Xiaomi NVidia GPU. Some want retina screen, some want resolutions with better Linux support.
If you don’t like it don’t get it. But don’t nitpick to try to find some way they aren’t exactly the same: no one thinks that they are.
Nevertheless they are both high quality, i7, 16GB aluminium notebooks which suit developers.
I think it’s more like 2.5 to 3 times cheaper than 3 to 4, but it’s pretty easy to find.
