Googles insurmountable challenge is that the habits of mobile device users are evolving and moving rapidly away from traditional search.

The successful Apple app is essentially a tiny search engine in a box
and ONLY for apple products for their apple stuff.
I recently went to buy a cell phone to have my land line number and replace the cell phone and land line. I was sold an I phone. The salesman cleverly determined what my wife and I were paying for phone service on 5 lines and sold us cell phones and internet for the same price.
It is quite useful and for a semiretired person has far more capabilities than I can use. It does deliver phone messages and voice mail while on the road and has voice mail and when I don’t want to answer. It is superior to my old cell phone in numerous ways.
I have searched through the apps and find most to be of no value and many just plain trash. There are some that are variations of the stock IPhone aps and perhaps improves them for specific requirements.
The elimination of the static land line for total mobility is a big big plus while maintaining the number my little business has had for years and years is very good.
