In general, he is probably right about the OS, not necessarily being dead, but being irrelevant. As long as you can do what you need to do, the brand of OS/machine is of no matter. I would say the same goes for any computer--as long as you can do what you need to do, what ever application--full fledged office product or a hampered version (e.g. Microsoft Works), it makes no difference of the OS, because most of us never do anything below the UI. Sure there are differences in the procedures and capabilities in the OS, it then becomes the user's responsibility to find a unit that will do what they want to do.
