Linux users love to claim the android market.
Linux doesn't run on cell phones, a proprietary derivative of it does.

I wish Linus had had the insight to base his kernel on more modern concepts than UNIX.
Linux has just become another monolithic beast.
As to large firms using it, why wouldn't they adopt free UNIX?
As to individuals being asked to us an OS with UNIX roots?
Personally, I find BSD based OSX to be far easier to work with.
You are confusing Linux with GNU again Jim.
Linux is not a clone of the UNIX operating system, it is a clone of the UNIX kernel.
GNU is a clone of the UNIX operating system that is commonly used with the Linux kernel but also other kernels too.
