It's not always on and it's not WiFi, it's cellular "3G". You can pick up the signal anywhere your ATT cell phone would. Same for the Nook and DR800SG (both connect to Barnes & Noble via cellular). Of course the 3G version of iPads coming out soon are cellular wireless too.
My enTourage eDGe is WiFi and needs a hotspot. I connect mostly through my home wireless router. I'm not sure what other e-readers have WiFi. There are quite a few that have neither 3G nor WiFi, however (like my Cybook).
All of them, 3G or WiFi, have the option to turn the wireless off. That's a must for air travel, after all. And for saving battery life too. I never turn on my Kindle 2's wireless unless there's a purchased book ready for download.
Hope that helps.
