Sam Makovech of Ars Technica reviews the 8Bitdo Zero 2 ([amazon_link asins='B081HML6MP' template='PriceLink' store='boingboing' marketplace='US' link_id='7a15fb11-3ba7-49a2-9bb4-d41d4776fee6'] on Amazon), an adorable gamepad controller you can use with a Switch, PC, or Mac. His overall impression of the meant-for-travel gamepad is favorable.
From Ars Technica:
To my pleasant surprise, 8BitDo starts this gamepad off with a crucial emphasis on its D-pad. At roughly the size of an American dime, this small D-pad is comparable to some of Nintendo's smallest takes, like you'd find on a GameCube controller or a Nintendo 3DS console. But unlike those offerings, 8BitDo allows its Zero 2's D-pad to protrude ever so slightly farther from its body. Pressing down on any edge of the D-pad offers a full 2mm of action, and this has a satisfying sense of travel when a thumb is in its depressed, rounded center—built for the sake of neatly rocking from left to right or up to down.
The D-pad's quality was borne out by my own feverish Tetris testing, which worked whether I rapidly tap-tap-tapped in one direction or pivoted to a crucial "up to fast-drop" maneuver in newer Tetris games. When I imagine various times that I might rely on the Zero 2 as a controlling option, I think about how a good D-pad is the primary differentiator from other on-the-go options, whether that's a spare Joy-Con turned sideways, a weak laptop's keyboard, or a phone's on-screen buttons. I'd rather play Tetris or Super Mario Bros. with my thumb on this D-pad than relying on those other options.
