Kinda weak is not the same as being weak. Also, how many people will truly "need" more than it offers? Take me for example. I am still using a MacBook that I bought brand new in February 2009. That's 6 years ago. It has a total of 4 gigs of RAM and is currently running OS X Yosemite without any issues. Getting the new MacBook to replace my old MacBook after 6 years makes sense, and the new MacBook will be more device than I "need" being that my current 6 year old device is sufficient. Know what I mean?
There are too many trade-offs with this. I prefer 2 year old 2013 MBA over this one tbh or rMBP.
edit :
Let me clarify this a bit.
More resolution = more stress on GPU = lesser performance and also difference b/w performance of this GPU and previous ones isn't very big to compensate high resolution performance loss.
Core M = weaker performance compared to i5 processor.
Battery life is lesser than MBA.
Force touch didn't seem to work quite well according to some people who got a slight preview. (relative to Apple' high standards).
Almost same price considering only 12 inch screen size as opposed to 13 inch screen size.
Only one port and Adapter cost $79 (more than Apple TV !!)
Sorry, too many trade-offs.
I currently use a 3 year old low-end laptop which is going to be replaced in 3-4 months and I waited for this new MBA and I am not so impressed with it. I may go for rMBP or normal MBA.
