Well, Google now knows my wifi password too, as last week I got one of the new Google (LG) Nexus 5 phones.
Admittedly almost anything was going to impress me after my very wheezy Nokia 5800, but I'm so far very pleased with this new phone, everything is so fast and pretty much just works.
In some ways, my old Nokia Maps was better than the Google Maps for SatNav - Nokia had speed limits for every section of road, and would warn you if you were going too fast. Don't see that option in Google maps. But Google speaks the road names much more clearly and usually pronounces them correctly, unlike Nokia which sounded very false. But then it was a bit old.
Kitz you mentioned that the navigation voice was a bit quiet, I've found that too - in fact on this phone there's an odd inconsistency - some audio apps give you decent, if not loud, sound. Others are very hard to hear (through the built in speaker anyway).
eg iPlayer radio can sometimes sound a bt too loud on full volume, whereas iPLayer for TV on full volume seems too quiet all the time.
One of my interests is satellite TV, watching TV from other countries and also just the "challenge" of receiving more obscure sats. I've just downloaded an app that uses the phone camera and geolocation, such that when you view the screen, you see the sky in front of you (and trees/buildings etc that are in the way) via the phone's camera, but it also superimposes the location of satellites in the sky.
Thus you can determine if a tree or building or simply the horizon is preventing you from receiving a given satellite.
I am truly living in the future.
