Stripped of openness, it no longer possesses the quality that elevated Linux to its status as the second most popular commercial OS. I'm confused here.. Which flavour of Linux are you referring to as commercial, and which are you referring to as the 2nd most popular OS? If you're talking about "Linux" as in all Linux's put together, then you'll have to lump that in with all variants of other UNIXs put together, too.. Which puts Linux at a distant third behind the various flavours of BSD, of which Mac OS X makes up the majority share.. Stripped of its openness, Mac OS X HAS accomplished something in three years what Linux hasn't been able to do in over ten - make a variant of UNIX usable to the masses.. The open source community is squarely to blame for that.. Ten programmers, armed with a project manager, a plan, and a direction, will always accomplish more than a thousand un-qualified, directionless programmers working to customize the OS for their own personal gain.. Why else would I have to drop to a command-line simply to install Flash Player on my computer?
