i mean, the BR still works quite well, i'm a new player to it and it's actually one of the few online games that doesn't require you to have already been playing for 10 years
it doesn't look like a standard m.2 (looks more like a wireless card interface), and i highly doubt it would be user upgradable even if you had the right connector. but still, means there might be possibilities for upgrades even if it's through apple
