just get a usb charging mat and plug it into your laptop. then take a look at how big it is. then add that size to your laptop. then ask yourself if this 15% bigger laptop is something all the other people want, or would they rather have more battery/cpu/ram for that 15% of space. They probably won't. But they don't want the wireless charger in that space either. They want the smaller laptop.
