Yeah, I'll say others are innovating when they beat apple at design and engineering (ie. thinness and lightness). I doubt they will soon though. I don't think 1080p smartphone screens are very innovative, unless they can be proven to be substantially better than the ones we have now. It seems that the DNA sacrifices brightness and color saturation for a hardly discernible gain in sharpness. And the performance/battery hits don't seem very worth it.
I'd be all for 440 PPI, but I don't want any compromises. That's why I didn't buy the iPad 3, the tech just didn't seem ready yet.
I cannot recall a single post of yours touting the innovation of thinner and lighter non-Apple devices when they came out during the 4 and 4S era. You seem to qualify "innovation" as something that's improved that has practical purposes. By that rationale, there are tons of innovation with the competition. Just to use one example: you often berate plastic, but plastic has very many functions (allows SD expansion, battery expansion/replacement, allows for NFC, allows for customized backs). How come you don't tout it as innovative?
As I said, moving the goal posts; lowering and raising the bar for innovation as you see fit. Hard to argue against that. So be it.
EDIT:
I just wanna say that the term "innovation" is tossed around way too much. It's such a subjective thing, and difficult to argue. Is Android 4.2 innovative? They added PhotoSphere (basically just Photosynth), lockscreen widgets (OEMs have had this), Quick Settings (ROM community and OEMs have had this), Gesture Typing (Swype), and that's about it. Is the Nexus 4 innovative? No...unless you believe taking less profit is innovative.
If 4.2 isn't innovating (fair assessment) than iOS must be... whatever is
less-than innovating! Keep in mind, Apple's core philosophy is innovation.
So if Google adds things that others have, you wouldn't call that innovating. But if Apple does that (like making a device thinner or lighter; things that were done many times before by others), you call that innovation.
No words. I'll take Google's "innovation" over Apple's "innovation."
