1) Scrolling of long artist/album titles. Ideally, the item you're hovering over would scroll while browsing. Or, if this is not possible, allowing the user to have a setting to turn on scrolling of the artist and/or album in the "Now Playing" screen.

Here's why I want this so bad. When I browse by album, I see:

Promo Only Mains...
Promo Only Mains...
Promo Only Mains...
etc..

which actually are:
Promo Only Mainstream Club June 2003 (Disc 1)
Promo Only Mainstream Club June 2003 (Disc 2)
Promo Only Mainstream Radio February 2003

When I have several different "mainstream" variants and months, I have like 20 items in a row in the listing that look identical. I can't tell what's what unless I memorize what songs are on what compliation. Even when I play the album, the "Now Playing" screen is just as useless. It only gives me a few more characters:

Promo Only Mainstre...

2) On the fly playlists. This has been implemented in the 3rd generation iPods. Will Apple ever include this feature in a future software upgrade for older models?

3) No line out. This is far and away my biggest gripe. I almost didn't buy the iPod because of this. I fell in love with the size and simplicity of the iPod, but I still absolutely hate the fact that the signal coming out of the iPod is speaker-level. I can't stand have to play with 2 volume controls, etc

Does anyone know if the line out that's on the dock of the 3rd generation models works without power running to the dock?

Also, I wonder if someone - like the people who make the TransPod - are going to figure out a way to make use of the slot on the bottom of the iPod and harness the line out like the cradle does?
