I'm using a MacBook Pro 2016 for dev still works great, and its still better than every windows laptop available now. The touchpad itself is still superior - its crazy when you think about it. I know people on their 3rd or 4th windows laptop since I've been using mine. I tried a M4 recently and its battery life is fantastic, and its faster so I'll probably upgrade when this one dies, but it still works well.

Edit: just did a google and it seems I can still sell it for about $600AUD, I don't know how anyone is buying a non apple lap top.
