Actually, I was thinking of a way to zoom by using a slider on the screen so I can do it with one hand (thumb). I've started to adopt the one hand method of zooming with my left land by pinching with my index finger and thumb with my other three fingers holding the iPod. Yeah, I'll drop it one day, but I don't have a chance to always have two hands available and if i'm browsing something, it would be nice to be able to zoom with one hand.
