Honestly, I'm not even an Apple fangirl and that thing is a great computer. I bought one for work and it served me better than any other $999 computer ever did. It's apparently $599 now? Great value, in my opinion.
Having just switched up to the M4 air you're not wrong. Unless you have the 8GB version and it's causing you memory pressure (which it may not be), or you really need that extra display output (I did), it's a wonder machine still 5 years later.
Also, that wedge design might be peak laptop. It's just soooo nice when lifting off a surface. I know that sounds ridiculous but the attention to detail that went into that design is next level.
Even though I'm not in the market, part of me really hopes the MacBook SE (or whatever they call it) uses the wedge design to clear chassis parts like they did with the SE iphones (although I doubt it).
