Are they waiting until USB 4.0 is mainstream before making 3.0 available? That is really annoying.
The question is: is there any point to going to USB 3.0 on a mobile tablet right now? I don't think the current generation of built-in phone flash would even saturate USB 2.0.
USB3 should be in both iPads Pro, it is just silly that it's only in the 12.9, especially since it shipped first.
Although it's in the 12.9, it's not usable yet. It requires a 3.0 Lightning cable which doesn't exist yet. I have the 12.9 and the only 2 things I dislike about it are the lack of 3.0 and the stupid Apple file-system abstraction not allowing direct USB file copy.
The NAND inside the iPad Pro 9.7 can read/write at 250MB/s, USB2 is 480Mb/s. So the iPad Pro can already saturate USB 2, four times over. And since USB is burst, that 480Mb/s isn't even the sustained speed.
USB3 should be in both iPads Pro, it is just silly that it's only in the 12.9, especially since it shipped first. I'd also like to see TouchID 2 in there, it's just so much faster.
What's wrong with the iP6/6+?
Outside of these highlights, iOS is noticeably faster on the iPhone 6s. Im not sure what caused this, but the move from iOS 8 to iOS 9 caused the iPhone 6 to have noticeably more dropped frames in areas like the multitasking menu. Im not sure why this is the case but at any rate the iPhone 6s is noticeably smoother when using iOS 9 than the iPhone 6. I suspect that the addition of even more Gaussian blur effects in iOS 9 is really whats causing much of the frame drops occurring in the OS. The addition of new data sources to Spotlight causes noticeable lag to the iPhone 6 but the same isnt as obvious as it is on the iPhone 6s. One might notice that there's no discussion of RAM here because I didn't notice any problems with memory running out in the course of my use.
This from the 6s review:
