"The iPhone has a camera but not the iPhone."

Just to nitpick

Heck, even though it'd be an "outie" I'd love a thin little bar with speakers on it because that's a key difference between the iPhone and the iPod– The ability to share some music or video with one, or many people, without wires.

I'd even buy one of those little microphone add-ons like the Belkin Tune Talk, Griffin iTalk Pro, or the XtremeMac MicroMemo if it meant I could share my music, or even listen to a tune without forcing me, and others, to don headphones.

I would be all for a speaker add-on for the Touch, especially if Apple (or any random third party) found a way to include a few megs of RAM in the thing. I don't know how bulky that would be, but if you can fit a gigabyte of storage onto a card the size of your pinky's fingernail, why not do the same for memory?
