Apple decided not to put GPS on the iPod. Period. Purchase an iPod Mini then if you want GPS. GPS does use a lot of battery.

GPS requires a 3G network to connect to. 3G networks require a "data plan" and therefore a monthly bill for that "data plan". You also must have an account with a company that offers the 3G network service, like a cell phone has.
Usually you would simply purchase an iPhone, rather than an iPod, if you are looking for a device with that type of service requirements.

I believe that you are incorrect. GPS doesn't require a 3G network at all. If your GPS app needs maps (like Google map) then you need to communicate across the net which would require wifi or a cellular service. On the other hand, if you are using a GPS (like You Need a Map) then the GPS map data is downloaded when you install the App.
I have a 3rd gen iPod touch and an external GPS receiver from Dual (looks like a cradle for the touch) which allows my old touch to use GPS.
There is no monthly charge for GPS. It's 'free'.

footie, you are correct in that GPS is indepentent of cellular service. However, Apple only provided GPS in their devices that have cellular.

It would be useful if Apple published battery drain specs for the different services like Location Services. I would be surprised to learn that GPS-based location services was a lot more than wifi-based location services. In wifi-location services your wifi is always on and wifi both transmits and receives, whereas GPS just recieves.
From a cost point of view Apple is charging everyone $100 for the increment of 16 GB of flash memory that's available at retail for about $10. Since they go to the trouble of having two different versions of the ipod touch, why not keep the sparse functionality of the current one, up it to 32 GB and move the ipod touch high end to the ipad family.
I still think it's pretty dumb. The iPod Touch is really a iPad micro now.

There's no direct connection between cellular and GPS. Apple made that decision on their own and it's now evident that neither cost nor functionality are constraints.
Garmin, Tomtom, Magellan all make GPS receivers that with touch screen displays as big or bigger than the ipod touch, with all of the maps inside, 8 GB of memory - no cellular required. These sell for $100 or less.
I much prefer to know where I am through GPS without telling ATT, Google and Apple where I am, don't you?

You can purchases a Mini with cellular/GPS and never activate the cellular service. That way AT&T and others will not know where you are.
