Maybe not regarding most usability questions.

However, the iPhone has a built-in speaker, of course,
so you can at least hear the music w/o earphones...

OTOH, none of the iPods so far had a built-in speaker,
and virtually none of the competitors has a built-in speaker,
so you could have been prepared;-)


On my Nokia 770, I used the zoom button very often,
because the default font size settings for Opera are far from optimal for me.

I don't use the zoom buttons very frequently nowadays,
since I sent my 770 to retirement...

HTH
