The plusses of a non removable battery are way better than the plusses of a removable one.
First of all, there are ways to soft reset devices without a battery pull, so that point is null.
Second, the reason removable batteries have bad charges is because they are removable. Building the battery into the phone make as it more efficient and allows a physically larger space to be taken up by the battery.
It also vastly improves the design of the phone, it not only looks better, but is also sturdier as a result of being able to be unibody.
I get people wanting a removable battery and that's all well and good, but don't be deluded, removable batteries are less efficient in power transfer and in capacity for their use of space.
