This doesn't actually address any of his points. I feel like you could change the "4" in your comment to a "5" in a couple years and feel equally justified.

If anything, it's a bigger sin today now that Android has been a player for so long. Things have improved. I guess. But the biggest issues (back button, notifications, messaging, the half-baked shovel-ware app store) seem pretty persistent.

Battery life is marginally better. Most of the benefits eaten up by bigger screens (I'm not complaining much as long as it gets me through a whole day: I just bought a 6.4" Android). Getting rid of the dedicated Search button was a step in the right direction. Swapping the "Options/Menu" or whatever button for an "Open Apps" button was definitely a win. Some wins in some of the OTB apps (Camera). But some noteworthy losses as well (Messages).

It should feel like an alternative. Not a compromise. And too often that's not the case IME.
