Google has already submitted a Maps app for the App Store so that won't be an issue for anyone unhappy with iOS Maps. As for the phone being a failure, I suggest you take some time with one. After using an iPhone 5 today I can safely say it's the most impressive piece of mobile tech I've ever used. The processor outperforms Quad Core and dual core S4 Krait processors with double the Ram. That's in benchmarks and actual use. The 5's browser opens pages in their entirety in about 2 seconds and apps open instantly.
The screen is gorgeous, the speaker is the best available on a phone at this point.
As far as tethering, that's done by carriers. The only phones that can pull it off nowadays are Nexus devices and some other unlocked international devices that don't register as Smartphones with the carrier.
Apple vs Android will always be a battleground, but the iPhone 5 is a game changer. For those that say it's a stretched 4, again you need some hands on time. It's super thin, extremely light and feels like a million bucks in your hand.
I've used every OS extensively, and I always go back to iOS. My last phone was an unlocked Galaxy Nexus and I rather enjoyed it. The 5 blows the doors off of it in actual usage.
Nothing else touches the camera on the iPhone 5 either in actual usage. That's in picture quality and the speed it can take photos. Specs are what Android fans keep in their back pocket for debates such as this. Specs are great on paper, but laggy performance on new Android devices (including the GS3) are proof that they aren't a be all end all. The 5 has assured that I will not be jumping from device to device any longer.
