I would buy the Steam Deck OLED just for the battery and screen alone... but damn, the LeGO is nice (that and there's no official distribution of the deck here)
I want a handheld with the form factor of the ally, efficiency and battery life of the deck oled, vrr, hdr, oled, 120hz, 1080p, rog allys screen size (without the bezels so like 8inches maybe) and a 8840u (or a z2 extreme if that ever drops)
