As of yesterday, the Nintendo Switch has been available at retail for six months. In that time, it’s become clear that the Switch is a smashing success, at least at launch. Though we won’t be able to say if it will take a place among the console greats for quite some time, it certainly is off to an excellent start. This is evidenced by the fact that even six months out from release, Nintendo is having a tough time keeping it in stock across the country. That doesn’t bode well for the holiday shopping season, but it’s at least a good problem to have for Nintendo.
