I'm thinking of buying either the 大辞林 or 大辞泉 for my iPod - but which way to jump?

Which has the better interface and are there other differences I should be aware of? (I remember Katsuo reported that the Daijirin's incremental kana search is broken under iOS4...)

I haven't tried the 大辞泉, so can't compare it with the 大辞林. This is just to say that the latter has been updated today, and incremental search now works with iOS4.
