I do agree that, beside this problem, this is a very good device, and I said it several times, especially about the upgradable aspect that is rare on a tablet. This is precisely why this is so frustrating: This is not the battery drain that bothers me. If it drains at a normal rate DURING USE, then this is normal use case that is acceptable. What bothers me is that it actually DOES SOMETHING WHEN IT IS SUPPOSED TO BE OFF. There is a program running in the background, doing things, executing code, while the device is shut down. And you may suspect that this may eventually be used to reactivate the machine while off, if an attacker can design a way to do so. As a developer, I prefer to have complete control on my machine, and be able to know what it does, and this includes the ability to completely shut it down. But I understand that others can actually live with this.
