It’s exciting in general to get yourhands on a gaming machine for the first time, asI did this morning in New York at Nintendo’s first big Switch preview. But it’s doubly fun because Switch, coming March 3 for $299, is sounique. At its core, it’s a tablet with a 6.2-inch screen (a little bigger than an iPhone 7 Plus). You can slip it into a dock that hooks up to your TV if you want to play on a big screen.
