That’s because the 13" MBP with AS released today is a replacement for the previous low-end 13" MBP (2 TB ports). The high-end 13" (4 TB ports) is still Intel all the way and will likely stay that way until next year when also the iMac and the 16" MBP go AS.
As with the previous low-end 13", I’m not really sure who the target demographic is. It’s got a tad more horsepower than the MBA (due to its active cooling and increased thermal envelope), but it offers hardly anything really compelling in comparison. It is however $250 more expensive (8/512).
I wouldn’t hesitate at this point to recommend an AS MBA to a casual Mac user. It’s apparently got great battery life and really good all-round performance. Same with the mini if you’re not looking to do serious number crunching.
If you’re a more pro-minded user who needs lots of performance from a small package, I would however wait until next year when the high-end 13" MBP gets released. By then also much more software will have caught up and you’ll see an even greater boost.
I plan on replacing my few-months old 10th-gen Core i7 13" MBP (32/1000) with an AS 13" MBP once it’s released next year. I’m looking forward to better CPU performance and improved battery life. Compared to my old 2013 Core i7 13", the new Core i7 13" battery life kinda sucks. I’m still hoping the new AS MBP will then be 14" with slimmer bezels similar to the recent 15" → 16" MBP improvement.
