you mentioned that you still like your apple stuff earlier :)
but any way , 3d in paint ? well I can't even try to do stuff with it , simply it don't support layers ..
re: integration into PowerPoint..... keynote have 3d charts and shapes ages ago .
re:AR and VR , did they made it or just talking about it ? you know , five years ago they talked about their great hologram AR thing and still is not available yet ....
re:touch bar .... for me a touch bar is more effective than a touch screen , with touch screen you won't save time when working (it will be slower than normal mouse/touch pad ) in the other hand , a touch bar can make work much faster (just interactive shortcuts )
but you know , every one has a preference , some people will like product X and others will like product Y , this very normal :D
