Acchi Kocchi. just two oblivious kids crushing on each other in that "it's obvious to everyone except them" sort of way. format wise it's skit based, almost like if Lucky Star had been written to be more wholesome and less crude.
btw, i'd also appreciate recs from any other Acchi Kocchi enjoyers in the thread 😉
i think by "we" you mean the manufacturers? AFAICT they just gave away the game: the push for thin phones was more from the supply side than the demand side. not saying people don't generally prefer thin phones -- just that the preference is probably weaker than has been made out to be.
that said, i think it's more fair to compare things like cubic volume and weight than just the thinness. a 1/2" thick full-size phone would be uncomfortable in my pocket, whereas a 1/2" thick wallet-sized phone might actually be more comfortable than a traditional smartphone.
