I'd totally buy a Switch....if it was actually humanly possible. I also wanted to by a NES Classic, which also proved impossible. Solved that problem with a Raspberry PI. I loathe Nintendo's idiotic business practices of artificially limiting supply when there's huge demand. They have something like 2 million Switches for the launch window. 2. Million.
If you're ok substituting a Pi for the NES Classic, you might want to try substituting a GPD Win [1] in place of a Switch.
Depending on the games you play, the GPD Win is an excellent portable computer for playing games. After I saw the opening title list and pricing of the Switch, I just ended up buying a GPD Win and play a lot of my Steam library on it. For the games it can't play, I can still use Steam Streaming if I'm playing with it at home. I was pleasantly surprised with some of the 720p frame rates I could get with it. There's a list of games that are playable in the GPD Win's Reddit group [2].
I didn't have much trouble at all getting a pre-order...I just used nowinstock to track all the stores in the US that were accepting preorders and jumped on one as soon as it was available. Took me maybe 3 or 4 days of trying.
By all indications, you should be able to pick some up from walking into stores. While there is probably not a huge supply, there seem to be a lot of units available for walk-in customers. YMMV though.
