Mr self destruct (but the board were the real idiots)
Steps in how to destroy a company (mobile phone side)
1) Publicly bad-mouth the existing main (struggling mostly due to a dated UI) offering for smart phones whilst simultaneously relying on it for high end revenue for the next 2 years (burning platform speech*)
2) Realise there are no credible alternatives coming out of the Nokia pipeline for the next year and a half (of course you may very will think that if 1 came after 2 then it looked like someone deliberately sabotaging Nokia...)
3) Pin your high-end mobile hopes on windows platforms.
...now sit back and enjoy the fruits of your labour.
However, the real accolades need to go to the Nokia board whom agreed to pay Elop a fortune even if he completely messed up (which he duly did).
As sympathizing for Mr Elop himself - seriously? He got paid handsomely for failing spectacularly and impacted a lot of people whilst displaying no observable traits of caring about those impacted by his decisions. So obviously we should all give him a hug now.
