Bias is when you believe everyone else is just like you, and then go on to base your entire perspectives in life based ONLY on that which is immediately visible to you from your unique perspective.
Looking at objective demographic data, however, is where you start to see the "big picture" and realize that your own little world is not, in fact, the "big picture."
Per ComScore, Giga, Flurry and many others, the average US consumer with a smartphone now uses it about 2.5 hours per day. Most of that (80%) is spent using Apps.
This is for both iOS and Android. Android users, however, use Apps much LESS than do iOS users. Again, empirical evidence...not personal conjecture based on asking Aunt Mae and your cousin how they use their phones.
You can believe what you want. I tend to believe objective data based on scientific analysis versus forum posters who post a lopsided opinion.
