I find the GPS on my mobile very useful actually. Although it's not a SE phone (Nokia), it has aGPS (asissted GPS) and with the help of a network connection, it can lock onto a signal from inside my house - not pointing through a window of anything in under a minute, sometimes faster. If I turn off aGPS and jsut use the GPS alone, it's still pretty reasonable and can lock onto a signal in around 2 mins.
