While a big corporations like Microsoft is a good thing for Bitcoin users, but when one sees the link it's only for very limited uses, so not much of use if one actually sees it, however if one looks for the long term then it could actually be very much profitable to all of us, if Microsoft is accepting it, then the big corporations are not far behind from accepting it. Say apple or Google starts accepting it, that will be huge and change Bitcoins for ever, as of now not much for Bitcoins in this.
