The real issue here is CHOICE.
In 18-24 months when a battery exhausts its lifespan you have CHOICES with a removable design. Just as we have choices today, whether to carry a battery bank or carry reload-able cells. With a V10 I have multiple choices at my disposal... Qi wireless charging, 9V quick charge, 5V slow charge, or even a powerbear / zerolemon FAT-batt upgrade.
Human beings are creatures of habit. Change and having to make decided choices generally makes them uncomfortable. Having too many choices can result in a form of option paralysis. Thats just the human psychology of the individual... some people are just more comfortable being told what to do, rather than choosing what to do. Of course... a large percentage just have no preference, and thats OK too.
