A large majority of "professional" software engineers use google email on their phones. And I've used gdocs etc at times on my phone continuously over the past 20 years, and many of them i was working at microsoft. Apples sales increased for a long time, even though google's sales increased faster apple was, i repeat was capturing most of the profit. We'll see if that happens. I expect several companies out of china to take the android market from samsung (still using android though).
