Ok.... here is my take.
Nothing wrong with these Snapdragon chips, they are great, they do have good efficiency, certainly better than Intel and i'm sure some of its compatibility issues will be ironed out in time, but even so it does not make them the best CPU's for the job, or most jobs.
My problem is they don't belong in £1200 - £1500 Laptop's, this is Microsoft trying to normalise something that isn't great for a huge amount of money, they want us to learn to accept the En____tification of products for profit, No!
These things are fine in £300 to £600 laptops.
