Damn is the screen protector thing true? My switch does get hot when docked.I was in the same predicament as you were. I decided to buy the switch because of the rumoured hardware revision. Nintendo always bundles a console with the pokemon games and they are likely to bundle the new console with the new pokemon game.
Buying the system now is letting me do the following:
1. Purchase physical games that may be out of print by next year (super bomberman r, snipper clips, superbeat xonic, my hero one's justice)
2. Redeem the gold coins for games where applicable (bayonetta, crash bandicoot n sane trilogy, super mario party)
3. Learn everything about the console and how it works to mitigate damage on the rumoured console revision (having the switch docked with a screen protector is melting the adhesive on the bottom right of the screen protector)
If you really think about it, you're going to have a backlog of video games to play whether you buy the switch now or later. Buying it now at least gives you a head start on attempting to manage your backlog. I'm 13 games in already and I doubt I'll play them all to completion.
So is it a bad idea to get one? How about tempered glass?
