It's one of the things the iPhone UI is sorely missing. When in the iPhone app, and scrolling through one of my long playlists, It can take an age to get to the song I want. Yes, I know there's a search option, but it doesn't search via the playlist, only the library, or album the song is in. Whilst using Apple's Remote app the other day, I noticed that when in the same playlist, there's suddenly a scroll bar! It's also needed in Safari, when browsing a long webpage. I know and have the QuickScroll app from Cydia, but that becomes useless in the iPod, because it requires you to tripple-tap, on something that isnt clickable(the whole list is clickable in the iPod).
