Zero. Haha. My brother is very into it, though. He's locked in for Zelda, Mario Kart, Splatoon, and 1-2 Switch. I'm happy about it because I get to use him as the guinea pig, since this time around we're not sharing a console (like we did with Wii U, Wii, GC, and every other one beforehand) and he was willing to jump in day 1 while I wasn't, mostly due to my budget and not being convinced that I need a Switch right away. I believe my bro bought additional controllers so those, plus the game preorders easily puts him in the $500 range once everything is paid for. Crazy. But, he was also the type to spend endlessly on additional controllers for Wii U and PS4 without a second's hesitation.
By the looks of it, I'll be having a damn good preview of the system without having to buy one myself. Gotta love enthusiast family members. We'll see if that translates into a purchase for me as well. As much of a Nintendo fan as I am, I'm still convinced that I'll be waiting until the holiday season to grab my own system. Time will tell.
