I don't know if this is from the perspective of having learned Mandarin in elementary school first or if Japanese folks feel similarly, but reading words like, e.g., だいがくいんせい versus 大学院生 is actually a little more annoying because I have to scan more of the line to read the word in question. This is notwithstanding the effect that hiragana has in highlighting grammatical structures; it's a lot like setting off Finnish case endings and verb conjugations in a different color.

At least, that's the reason why I prefer still having kanji around.
