I'm not entirely sold on the peripheral keyboard, but only because my fat fingers would press multiple tiny keys if I tried to type. I guess Liliputing implies li'l fingers 🙂
7 inch display has always been unusable for this form factor. I get that it's easy to integrate with the pi but when using a cyber deck as a laptop it's like trying to read a postage stamp.
HMDs like the Xreal Air seem like the better way to go: ditch the integrated screen.
