I've read several posts that suggested turning off wi-fi to extend battery life and I don't get why. My experience with wi-fi is that the phone rocks with it on, it's at least five times faster and if it's transceiving to/from my router that's no distance at all, 40-50 feet.
I have an iPod Touch (I know, the enemy, LOL) and it's running wi-fi all the time with no real loss of battery life. I actually got into the habit of using it as my de facto TV Guide which is something the Droid is going to be pressed into service for (it does have a nicer screen) but I'd think wi-fi on would save battery life, not burn it.
The way I understand the data transfers, the phone has to ask for data.
Phone: "Give me data, please"
Then the provider has to say "okay".
Provider: "Okay"
Then there's a total protocol where the provider and the phone communicate where they handshake and say "did you get the data?" and "I got the data" back and forth, which I'd think would take a lot less power on wi-fi than it does over a 3G network. After all, radios talking 50 feet don't need as much juice as radios talking several miles.
The way I use my Droid, which is near a Wi-Fi hot spot probably more than half the time, I'm keeping Wi-Fi on. The phone is faster on Wi-Fi, and I don't see how it really does anything but SAVE battery life.
