I recently bought an iPhone 6 to replace my iPhone 4S.
(As an aside, my wife will now use that iPhone 4S, and we’ll finally retire my original iPhone 3G from daily use!)
I’ve enjoyed it so far, and the new iOS 8, but there are a couple of instances of muscle memory that I’m still working on overcoming with the new device.
First, Apple has moved the sleep button from the right side of the top edge to the upper right edge of the device. The move makes sense given the larger size of the iPhone 6, but after a few days of use I still automatically reach for the top edge to put the phone to sleep.
Second, the iPhone 6 includes Touch ID, which uses the home button to detect my fingerprint. Again, after a few days of use I still press the home button and then swipe to wake my iPhone, even though a button press plus a lingering finger on the home button will engage Touch ID and get me into the device.
At a more minor level, the larger screen size is taking a little getting used to. It’s not uncomfortable, but my hands haven’t yet adjusted to the jump in size from the iPhone 4S.
It’s kind of fun to notice this stuff as it happens.
