Why iPod touch location awareness sucks

One of the best features of the iPhone is its location awareness. Using Cell tower/WiFi proximity and now GPS with the iPhone 3G, it knows where it is and can use this information in a growing number of location aware applications. In theory the iPod Touch can do the same using only wireless access point data, but unless you live in a city the service is pretty hit and miss. I live in a reasonably sized UK town and my iTouch can’t tell where it is.
