I wonder if Apple will ever be transparent about the watch sales. Regardless, I think it is safe to say that they are selling in the millions and is by far the best selling smartwatch. I could see (although I am not convinced) that the 6s numbers YoY will not be as hot, given that there is nothing huge in it (I love mine, but really if you have a 6 you are just as good). Let's see if the 7 comes out with something more significant. I would love to see them finally retire the home button so the screen size can increase without the phone size increasing. I also hope they spend a bajillion dollars on upgrading their services and integration points because that by far is the week link (even though in many ways they are still ahead of most others).
The category (iPone/smartphones) is so far matured that we should not expect miracles for the 7.
The chip speed and size will eventually hit a limit. Same for camera pixels.
More GBs okay, they should be at 256 already, but it's Apple.
Yes to bigger screen real estate over making the phone bigger.
While my 4S is still doing it, I will buy a 6S plus as soon as they are widely available.
Partially because my eyesight is getting bad and partially because I waited long enough to get a lot of better features. (I am not an update must have latest crazy person)
Maybe tweaking voice recognition.
Apple services is another problem issue they don't seem to address swiftly.
There isn't one service of theirs I like or use and pay extra for. Dropbox runs rings around them.
Apple Music nah, iCloud nah.
