Agreed....I think for the past two iterations, Apple has been mostly playing catch vs true innovations. Granted, there have been some very cool features they've rolled out, and integration with other devices has improved.
I think that accross the board most high stake players are simply trying to beat each other out with one or two killer features, versus true innovation.
Perhaps we're at that point in the product life cycle where things being stagnant, pending a new technology breakthrough for the wheel to start turning again (for Iphone, it was the touch screen and the concept of Apps).
But, what I do think is a trend amount many different industries is integration.... having devices go accross multiple platforms (Home Entertainment, Car manufacturers, Business Solutions)... so perhaps the enhancements are more of the software side than hardware.
