Phones remain a critical component of the Microsoft device portfolio and an important piece of our mobility strategy, but a restructuring is in order.

To align with our new strategy to enhance the Windows device ecosystem, we are integrating Microsoft Mobile Device Sales (MMDS) underneath the Consumer Channels Group (CCG).

If you bet on Microsoft, you are not going to ask anymore, 'Hey, where is the innovation?' The challenge going forward is how do we keep up with it.

We have been investing in building a mobile-first selling capability by establishing the Consumer Channels Group to strengthen and align the device-selling motion and to expand our impact with OEM, retail channel partners and our operator channel, and by extending it with our opening of Microsoft Stores.

My advice is to make acting your second career choice.

As an actor, you just want to work, and then you just want to be on a show or have a job that you love, and you hope that job will last - those things have happened. To have that platform to then talk about something that is very personal to me like marriage equality, it feels like a gift. I try and really respect that voice and not abuse it.

Being an entrepreneur does, of course, give you greater freedom than someone who is tied to a fixed work schedule, but you'd be mistaken to think that you're going to have it easier than your 9-5 counterparts.

I've worked in public education for 30 years - as a teacher, a lawyer and union leader. I've visited hundreds of schools and districts. I've seen leaders from the classroom to the national stage who have been willing to set aside their differences and do the hard work that's necessary to create real, enduring change.
