It sounds to me like you're describing not what "High-end smartphone users" currently expect, but rather what "High-end iPhone users" currently expect. Steve Jobs pretty much created his own concept of what a phone should be, and so now most of the industry falls over itself trying to create iPhone clones. Which, hey, I'm not going to argue with, as it has been kinda like a license for Apple to print money, but I'd really like to see some fresh new ideas out there.
