I have all my games installed on all my various hardware devices. I am not one for deleting, moving and re-downloading. That is archaic.
Speaking of which, the S2 needs real wifi. I hate how slow the switch is with download speeds. It has ways been a fraction of what all my other devices achieve.
S2 also needs better sound chips. Surround on the switch is very meh.
So hopefully Nintendo addresses a few additional things with the S2.
