Four sharp corners for the actual display and no notch are winning moves.
MacBook Air has double the RAM but is nearly double (>1.8x) the price.
Flash storage and memory compression mean that you can do pretty well running a single app at a time.
With that said, I hate that you can’t upgrade the RAM or storage.
I hope that at least one side effect of this is that developers will have a business case for performance improvement dev time, as those machines will become a juicy target, similar to video game consoles that may not have the best specs but are consistent and have a large number of units in the market.
