A very interesting article from IT-Analysis. It's written by Clay Ryder of The Sageza Group and is well worth a read.
The premise is that, just as today we don't have to ask if a system is TCP/IP capable, in the very near future Open Source software will be just as ubiquitous and 'assumed' to be part of the solution. And by the way, just as TCP/IP provided a base for the explosive growth of the network model, Open Source software will do the same for business.
Yes, I know that some network manufacturers are no longer in business but the reality is they couldn't adapt fast enough. The same will happen to software makers who don't adapt.
It's called evolution.
