The idea that you would water down any version of one of your best selling and most reliable product lines for the competition is so shortsighted. The goal is to give the absolute best user experience possible on any platform so your product gets the most respect globally. This drives people TO your platform. It's not a coincidence that the top 3 apps in the Apple app store yesterday were the Office suite or products followed by OneNote in 7th and can you believe Skype in 13th! That's 5 MS apps in the top 13 on the Apple store! The products WORK and that's why people want it. The product is ingrained in our everyday life and that's why people want it. Now they can be on whatever platform they want and get the best user experience out there. This is a brilliant move and one that is several years too late. These kinds of business moves will only help the product, the company and its shareholders by putting more faith and money into the ecosystem.
If you go to Bing News and have MS as one of your topics you follow you'll see that the naysayers have come out of the woodwork yet again to state that it's too little too late, that there are better alternatives, that it's not free, that there's no reason in this day and age to use a dinosaur program. But those opinions are starting to get shouted down by those who see the value in the product and, more importantly, are seeing how well the products and services are integrating in their day to day lives. And have you seen MS stock?
I agree there are shortcomings with MS products ON MS products but they will continue to be refined as the company becomes more unified. This is actually an exciting time to be part of the MS ecosystem and I can't wait to see what's ahead.
