Ignorant question: Does much actually make it out of MS Research? I've seen lots of interesting retrospectives on stuff that either failed or just has never come out of the lab (Singularity/Midori, accessibility demos showing phones reading restaurant menus to the blind, their tablet pre-ipad, etc.) but I don't think I know of anything they made that really grew up off the top of my head.
I didn't want to say this without doing a little bit of homework so I checked their Wikipedia page (https://en.wikipedia.org/wiki/Microsoft_Research) which doesn't list any accomplishments, just claims they have a lot of patents, and their main site has a publication index (https://www.microsoft.com/en-us/research/publications/?) but publication is not a good metric for ever seeing use.
