Microsoft reacts, in a future fear knee-jerk fashion that totally belies all their "we love Linux" BS they have pushed out of late.MS had actually yanked all their on-line Android Office Apps and published a schedule for the yearly cost for you to use your existing MS Word files, not thinking that they were 1) breaking the law 2) breaking their own license agreements 3) cutting their own throats.

=====================================
then just one day later .......Then, in true Micky fashion, one day later they said
"Woopsie, we really didn't mean it" and pulled it all back.

It does not take a rocket scientist to read this statement and figure out that something "incompatible" will shortly be found with all Chromebook based "non-Office 365" installations.
Read it and
realize that MS does not care to blatantly break the law or break their own license agreements, so they still have to figure out some "incompatibilities" to blame it all on. Some are being written and pushed to your machines as we speak ...... and yes, even on Chrome an automatic update can be pushed by the vendor.
"Our strategy has not changed. Office for Android is supported on Chrome OS devices via the Google Play Store. While Google Play on Chrome OS is in beta, we are partnering with Google to deliver the best experience for Chromebook users and plan to make the apps available on all compatible devices by general availability."
– Microsoft Office TeamMicky has seen the future, and the future is Chromebooks, tons and tons of them, running free Apps both on-line and local loaded. MS just realized this and karked in their drawers.
MS simply hasn't figured out a way to make lots of money off of Chromebooks yet.
=========================================
Thoughts at this point MS is suddenly showing a willingness to work with Google to get their old software fully ARM/ANDROID acceptable. Joining the Open Source FOSS associations and the Linux Foundations are moves that say MickeySoft realizes that they cannot go off into the future by themselves anymore.
Microsoft and Intel also realize they are NON-competitive (both combined and individually) right now and each has picked them a pathway off into the future that requires them to trim all the dead flesh off of their shrinking companies and to FOCUS all their energy on just surviving, simply by doing what does work for them (makes a dollar) and cutting all the rest.
Both Intel and Microsoft are seeking to form up groups of other older companies intending to break into these new growth industries.
The impact of the new 3-D memory types on this shifting equation is going to be MASSIVE --- it is shipping now and is going through the industry like grease through a goose wherever it has landed .....
What we are told by HP and their early systems tests are that a lesser processor product equipped with gigabytes of the new stuff will outperform today's best of the best by a thousand times or more. This is a very significant thing in an already shaky industry.
Andromeda is a real word now, and it was supposed to ship inside the planned Nexus 7 (renamed Pixel) replacement tablet. This tablet has been delayed (or cancelled ???) by disagreements on meeting the shifting price and volume and features concerns between Google and their supplier.
Google has wisely decided not to make it or ship it as it is, but instead to start a new project with a supplier who can perform to rapidly shifting agreements. Huawei also supposedly choked on leaving their name off of the product, and having it to be only known as a "Pixel" or "Andromeda" device as this was not the case when they signed up for the "Huawei Nexus" moniker.
Look to see lots of existing Wintel tech being sold cheap for Christmas, since if it isn't sold soon it will get strongly devalued next year as MASSIVE CHANGE waves come rolling through making the current tech stuff less desirable.
