When I first got my Droid X Android phone I was not quite ready to give up my Windows Smartphone yet. I wanted to find equivalent mandatory apps first, so activation was something I wanted to avoid.
So I thought I would turn the phone on and get used to it, and use WiFi for any internet connectivity to download apps, etc.
Seemed like I had to activate the darn thing before I could even use it. I felt this sucked since I had paid for it.
Finally I have found someone who knows how to use an Android phone without activation first.
