Just look at Ayaneo's absolute unit of a Windows gaming "handheld"

Ayaneo's Massive Windows Gaming Handheld: Game Changer

Ayaneo's Next II prioritizes raw processing power over portability, weighing 3.14 pounds and measuring 13.45" x 10.3"—more than double the Steam Deck OLED's weight and designed for lap-based or table-mounted gaming rather than true on-the-go play.
