How do cellphones change your life?

Yes you are always connected and people yak in restaurants.  Michael at 2blowhards.com makes another good point:

I don't use the land line often, but when I do it's often for very enjoyable 30 minute stream-of-consciousness yakfests. It's hard to imagine enjoying such a conversation on the cellphone, and I finally decided that I don't want to give up the possibilty of having analog conversations.

Is it down to the quality of the sound? There seems to be an ever-so-slight delay in the conversational back-and-forth on a cellphone. This takes a little getting used to, and it certainly interrupts the free flow of intuition and thought.

My main dislike: When you have a cellphone, it is easier for others to be late.  It is also harder to get people to precommit to exact plans in advance.  Too much discretion, not enough rules.
