I think Valve should continue to focus the Steam Deck series as the all-around PC handheld that has great battery life. SD2, will probably be Phoenix 30W performance at 15W, which I think would be great with the introduction of an even bigger battery (60 to 70wh).

There are many 7040u devices. But they are used with handheld gaming systems like the ROG Ally and Lenovo Legion Go.
