Good perspectives. The ability to create quick tweaks such as the IFTTT wallpaper recipe you mentioned is like a dream playground for tinkerers. Apps such as Tasker help take your Android experience to the next level. This type of tinkering is what I miss the most on my iOS devices. I am not a huge fan of the Notifications bars that appear with the repeating monochrome logos (if an app has a notification, a badge number is better than bunch of repeating logos in my opinion). The size comparison is also interesting. I am using huge devices on both OS (Galaxy Note and iPhone 6+) so going back and forth doesn’t seem that different. Occasionally I will use the double tap on iOS for reachability (one handed in a train or a bus).
