Hi Susan ! How are you ? I agree with you of course - I really think they are just wasting their time, but you know how these Conglomerates operate - they hate to admit they cannot compete in sectors they choose to enter.
Wasn't this push by the egomaniac - Ballmer ? For so many years Microsoft just bought it's way into things it could not produce with relative success and this type of arrogance lead to the smartphone market as well - it is funny.
Ballmer probably saw that employees were using iPhones and just couldn't stand it - still can't stand it and this illogical push to make ( purchase) their own was born. It didn't matter that Apple and Samsung had already cornered the market - they were Microsoft. Could do anything they want with enough cash to see it through. He (Ballmer) underestimated how difficult this would be and now Nadella is saddled with this bloated and losing initiative.
"Let's go outside the US and push the product" - well that strategy hasn't worked either because people either love the the phone they already have ( iPhone or Samsung ) or can already find a cheap substitute.
But I am not telling you anything you don't already know ! ; ) So now we must wait until Microsoft stops lying to itself.
