Re: If only
Just like the lack of biodiversity in nature, a single OS for everything is vulnerable to one glitch, or one virus, or one flaw, bringing everything down.
There is no reason for not having OS designed for efficiency for each device and having the look and feel tuned for that device also. What works best for a desk top, makes for frustration on a smart phone or fondle slab. OS optimized for touch screens on a phone or slab are hardly workable on a desk top on a desk in a cube farm.
