To nitpick, you'd have to compare with the similar model from when the MacBook Air came out.

The T410 (a brick with a terrible screen and battery jutting out the rear) or the X201 (a nicer brick and a tiny trackpad

I definitely agree with you that the current T470/80/90 is a pretty nice machine, it's wolrds ahead of what the ThinkPad was when the Air was 'new'
