Tech saturation won’t happen as long as there is room to further bloat the bloatware.
We will soon consider dozens of megabytes for an app to be tiny as the bells and whistles keep proliferating like rabbits. The old cellphones will be as though they were old landline phones as data capacities grow to terabytes.
Sorry just ain’t gonna use a cell phone as a computer. Just ain’t gonna pay 1,000 a year just to make phone calls and use a few apps on a smart phone.
