Besides old timers, who cares if it takes a couple more hours to deplete the battery?
Seeing as all these phones are pretty decent, from my point of view, I just want the greatest performance.
FTFY. In other words, it doesn't fit my use case ergo no one else can benefit from it.
Actually they missed the boat on this one
I see what you did there...
It is a marketing issue. It is saying to the general public: Microsoft products suck so badly that not even their own employees use them!
If I remember correctly, Microsoft had a smartwatch many years ago that could only tell the time if it had a Wi-Fi connection, I am SHOCKED that it didn't catch on.
I think that you have your math wrong. Number one, you don't know who you are comparing the face of so according to your schema you would need to do 10,000 * 10,000 comparisons, since you don't have a way to say "Oh! This is John Derp's face, so let's only compare it to the other 9,999 faces!". Also, you don't compare each face with everyone else's, you only compare with a list of known crooks (hopefully not EVERYONE'S face is in the system, although I am not sure of anything these days).
Then, assuming there are 100 known crooks in the 10,000 population, you do 10,000 * 100 comparisons and, assuming the same error rate of 1 in 1,000 you get 1,000,000 / 1,000 = 1,000 errors. Which is not nearly as high but definitely not ideal.
I henceforth name this the subset-birthday paradox!
