Greek and Cyrillic both have cases. And the Hiragana/Katakana distinction in Japanese is similar to case in some ways (including limited computer systems using only one)

Really? Those must be quite old as everything I've seen has both. But the difference between kata and kana is much larger than upper and lower case. It is rare to convert one to another as they are used to write different things. Only to look things up in a dictionary would you convert, and then you'd also be converting kanji to...

In Roman languages, very little is changed with all caps, though a few things become ambiguous depending on the language...

In Japanese, it could turn some foreign loan word into a native word with a totally different meaning...
