Time to move to iPhone 4?

Video calling is no longer a dream, it's a reality only a tap away. Not sure if that is the feature that makes me run to the shop. I rather like not being seen when on the phone. Rather not reveal what I do at the same time as I'm of course fully engaged in the conversation...
But the pure joy of holding a design masterpiece in my hand will no doubt make me continue my Applefication.
