I've been using the beta and all through it, there were no routing apps available for my area (San Antonio, so not exactly a tiny city, according to Wikipedia we are the 7th largest population wise)
Now that iOS 6 is out, I decided to give the Maps app a shot again. So I pulled it up, thought for a second since I am used to the old interface, clicked the wrong thing a couple times, finally got to where I needed to go. Scrolled through the saved list of directions that I've used in the past (very helpful). Clicked the bus button. Got routed to the App Store. There were 8 or so apps to pick from. Which ones sucked and which ones didn't, no idea. It's too new to tell.
Picked one at random, it's 99 cents, which is fine, I don't mind buying apps. It installs. And then sits there. Wait for a bit, maybe it's thinking or something (I'm on an iPhone 4, not 4S or 5). Okay, it's not. Go back into the maps app. It hasn't saved where I am, I'm back to the default screen. This time I remember so I go back to the directions. Click the bus button. Get routed back to the App Store again. This time the app I have says ROUTE. So I click it. It shows some introduction screen. I click the start button. Directions are blank.
Go back into maps, back to the directions, click the bus button, back to the App Store, click the route button, and the in the routing app, are two very different addresses than the ones I entered in to the Maps app. Scratch my head wondering how that happened.
Close Maps, close the routing app, delete the routing app, launch maps.google.com, get the bus schedule almost immediately.
I have no idea what anyone else's experiences are, but I have never been so disappointed.
Now as mentioned, I'm still on the iPhone 4, and I'm at the tail end of the contract, I believe next month is when I qualify for the upgrade without paying full price. I'm seriously looking at the S3, although the new report of the exploit via NFC is a bit troubling. I'm not particularly worried about the apps I've purchased on the iPhone. I've spent maybe 150 on apps on the almost 2 years I've had the phone, and as I was talking about it to a friend, he pointed out that as a smoker, I spend more than that per month on cigarettes, which really put things into perspective for me.
Never has Apple tastes so sour.
