Biggest disappointment ...
Is not just the errors - which can be fixed, but we have been used to Google maps which is great.
Satellite view - try zooming to Brighton, or just about anywhere on the south coast. On Apples maps you can't. You can on Google Maps.
Google Maps has Streetview, although someone earlier said it wasn't available on iOS it has been there since the introduction of iOS4.0 and is great on the iPhone and iPad. That has been taken away from us.
The search facility just doesn't work in Apple Maps. e.g. I had to go to 40 Bank Street the other day. If you type that into Google Maps it takes you to the correct building in Canary Wharf. The same search in Apple Maps suggests 40 Cank Street in Leicester. Nearly all searches fail to locate the correct address yet I have never had a problem with Google Maps.
We all know that Google couldn't license turn-by-turn navigation to Apple but surely anyone who wants turn-by-turn they use a proper Sat Nav app anyway rather than the poor implementation in either Googleor Apple Maps.
It doesn't work properly on the iPhone4 anyway (not sure about the 4S) as, apart from no voice guidance) it fails to stop the screen going blank (it does in the iPhone 5) so they have taken away a lot of functionality, given us inaccurate maps for what?
Apple have seriously dropped the ball on this one.
For those, including Tim Cook, that say we can still use m.google.maps -that lacks Streetview and is nowhere near as usable as the Google Maps app that we have been used to.
IOS6 is major downgrade Apple have released and I would seriously advise anyone who uses maps on their device to not upgrade.
But Apple are already releasing upgrades to their other apps that won't install unless you have iOS6.
I love my Apple devices but this could be a major factor in my next phone being my first non-iPhone for a long time.
