I expect PR and marketing people to do their spin jobs, but reality distortion has its limits, lol. For me, functionality is what will always count, on any device.
For lots of users, maps is a key feature on mobile devices, so it hurt to lose functionality. For something like Siri, it doesn't matter as much, because users hadn't come to rely on it and it didn't step back in functionality.
Personally, I didn't notice death grips probs with iPhone 4, but I did notice on iPhone 4S that I got fewer dropped calls and better reception even in the same parking garage that I use all the time. I also noticed that 4S has a much better (louder) speaker than 4. (I'd like to see future iPads get better speakers, too.)
