I've got my preorder in as well. I actually preordered 2, because I'm paranoid one will get screwed up somehow, lol. One online at Best Buy, one in person at GameStop.
I think the Switch is the perfect console for parents (and I mean for us to play, not the kids, haha). I barely have enough time to play video games, so the portable aspect is really useful just so I can play in different places around the house.
A lot of times after the kids are asleep, my wife likes to watch TV, which leaves me in a bit of a quandary. I'd like to play some games, but that means going to play in the bedroom. This is sort of a shame because I don't get much alone time with my wife as it is, so having the Switch will be nice so I can sit with her on the couch and play.
