This is a most excellent place for technology news and articles.
I have an M2 Air, and all mine is missing from that is the SDXC slot, third TB4 and HDMI, and honestly, it's fine. A third TB4/USB would be nice for when I'm doing my radio show and have to plug in my controller and mic while also charing my phone, but I already have a hub so it doesn't bother me.
That said, the limited ports on my M1 mini are quite problematic. Two TB3/USB and two USB3, but one of them is lost to a DisplayPort cable for my second monitor. So I have a desktop computer that functionally has three USB sockets, which ain't great. But again, I have a hub, so it's not a huge problem.
