The path forward for Linux is child's play
Linux has been growing in importance for years in the darkened server closets. In the server world, Linux's cost and performance benefits have trumped its early weaknesses (Ease of use, etc.), making Linux the heir apparent to the UNIX throne.
But that's the server, where geeks write software for other geeks. In the consumer world of personal computers and mobile devices, however, Linux hasn't fared particularly well precisely because the developers of Linux differ so markedly from the vast majority of the user population.
Linux developers, in other words, scratch very different "itches" from those plaguing most would-be Linux users.
It seems clear to me that, as Bill Weinberg astutely argues, the way forward for Linux is not in replicating Microsoft's desktop dominance, but rather in forging a new, consumer-friendly mobile Linux experience, one focused on the youth that are growing up mobile.
