While it is Microsoft’s last chance, I think they are doing the right things with the OS and App ecosystem. That being said, I’d like to see more leadership from Microsoft making experiences that truly take advantage of the diverse hardware we see in that ecosystem.
For example. Simple things like taking those Hasbro boardgames like Monopoly, Battleship, Chess, and other games like Risk where if you have an Xbox One, You can have the map/board on the big screen, but individuals can have their pieces/assets on a tablet, pc, or phone where they can keep their own hands/information private. They could have games where dungeon maps, coop information, etc on the Xbox One’s screen, but have a first person shooter experience on their own device. There’s tons of room for Party games that highlight the entire Windows ecosystem.
MS also need to bring back Party Mode for media. It should be an easy thing to synchronize music, videos, and other services where a "moderator" can queue up Netflix videos or even Xbox Videos where only the moderator has to own a movie can share a synchronized experience with up to 5 streams without forcing everyone to pay for an individual copy. Hell they could roll that into a feature for Xbox Live subscription.
We’ve seen cool things coming with the Surface HUB where everyone in a meeting can share and collaborate, but that needs to happen with other Windows devices as well. And the Hololense promise seems to bring that same kind of collaborative effort, but MS needs to make it truly exciting and work with Windows 10 for Phones as well as Window 10.
I do feel that if MS can’t get certain services right, they need to just decide to purchase a better offering than to keep slugging through bad development. We saw that with Skype, but I feel it may be time to fork over the money needed to buy Spotify.
The point is that if MS really wants to hit it out of the park, they need to make an ecosystem where the experience just is better and can’t be done by their competitors.
