The only way Linux ever becomes viable for the mainstream is when there is a single distribution that covers every feature and is as streamlined and user friendly as possible.

• No command lines ever for anything
• huge software compatibility
• hardware compatibility of the newest and oldest of hardware
• easy troubleshooting even your nan can follow
• and most of all: every Linux user agrees it is the best Linux distribution (unless you are into niche stuff)

So until even you guys can agree on one distribution being the best, it will not be the year of the Linux ever.–
