It’s actually more comfortable to hold than a Switch, in my opinion, and I wouldn’t say it’s too heavy, but I suppose that could depend on how your sitting/laying to play it? As far as the temp/heat goes, some games warm it up more than others, but even when it’s really getting pushed I’ve never been uncomfortable with the heat of the device. As others have mentioned, it’s honestly a fantastic handheld. ALL of my time has been dominated by Tears of the Kingdom lately, but I’m looking forward to getting back to the Deck soon(lol, it probably won’t be that soon, TotK is a massive game)
