1 year agoAlkaline batteries lose voltage as they drain, so 1.5V is at full charge but it drops down to about 1.2V very quickly and then stays at 1.0V - 1.2V for most of the alkaline battery’s operating life.
NiMH batteries tend to consistently stay at their nominal voltage (1.2V) through their entire charge.
So in other words, if you have devices that really expect exactly 1.5V per battery, they would only work with alkalines at the very top of their charge. Nowadays most non-garbage circuits should be designed to work just fine with anything above 1V per battery.
I won’t argue about whether this is dystopian, but the practical reason for the face projection is that they wanted to make this not just something you wear sitting alone in your basement, like most other VR headsets. They wanted it to be usable around other people, at a workplace, with family, etc.
Interacting with someone wearing a full face blind is just weird, so they thought that making the eyes visible would help make this a bit more socially usable.
I’m not sure that’s really going to work out — seems at least as awkward as Google’s failed Glass project — but Apple’s design decision has some merit.
