The lack of WiFi 7 is disappointing. 6E is fine but by now I'd expect 7 in new computers.
Sounds like maybe they didn't want to try and fit their new N1 chip this go around so they could re-use some components? MacBook still has the same broadcom chip. Or for a pro differentiating feature when the M5 Pro/Max comes out later. There's a rumored MBP re-design, so I'm guessing we'll see it then along with it having the N1 for WiFi 7.
What do you do on wifi that requires more than 10gb per seconds... on a laptop, you'd fill up the base model ssd in under a minute of download
Even pre-Apple Silicon, it's been a decade since users could upgrade MacBook's RAM or internal storage.
