I have one. (lumina 920).
It has three buttons.
I often find myself having to hold down the three buttons for 20 seconds. (this is the windows phone equivalent to ctrl-Alt-del).
If you miss blue screens, hangs, reboots, tacky graphic design, too many clicks to do one thing, and assumption that you are there to serve the hardware rather than the hardware serve you, then you are all set for...>>WINDOWS PHONE!!!
Also, don’t forget new Windows Phone OS revisions often lead to having to throw away the phone (now compatible updates). Unlike Apple/android where you can run the new stuff on an old phone...Very handy when you signed a 2 year commit, and 8 months later the NEW WINDOWS PHONE software does not support your 8 month old hardware. (this really happened).
Anybody that KNOWS anywhing or pays their own bills or is not REQUIRED to own a windows phone will not.
Meanwhile, BB has how many BB 10 devices? One with another on the way in the US. How many BB 10 tablets? Zero.
I have been looking at the new Z10 when my contract is up. My EVO has been OK, but so far not as impressed with Android as I thought I would be.
Wife has an iPhone and its about the same as mine.
