Microsoft wins on Innovation

why you believe this brand is winning?

What are they doing right?  

Is this something that has changed or have they always been "good/bad" in this area?
Is this a brand that you use now or have used in the past? If so, what do/did you like about it?
Has market/marketing research helped them? If so, how has it helped?  You can speak about activities you know or suspect they have done to guide their strategy.
Would you say that they are more "product-focused" or "consumer-focused"?  Why?
