Well, I guess this expansion card is soon to be obsolete. (Meanwhile, I will continue to enjoy my 1st gen FW12 as my daily driver until I really need mainboard upgrade.)
Well done, Framework, for listening to the community!
P.S. I am also very excited about the backlit keyboard. (Oh well, but it is kinda hard to part with a German keyboard layout… I blind type in English with the US layout most of the time but occasionally I do need the umlauts. Also, the German keyboard is the right amount of weird for me.)
