Windows Vista is not coming out soon. Now Redhat being the serious threat atleast at the server side, Vista's success is a little doubtful. Why will companies be willing to migrate to Vista is a question to ask. If it fails who will it be good for? Ubuntu is a cadidate to watch. No, no one will use Ubuntu on the server side atleast for now but with Vista failing, its highly likely people with change in their mind will change to other operating systems. Ubuntu is in that position. Why Ubuntu? Redhat is too heavy for desktops. Suse? Its useability is an issue. JDS? Do you even remember what it was? Solaris x86? Let the military use it. Other Linux flavors have more literary importance than anything else. Ubuntu tops the list in its' ease of use, useability, being wireless ready or just the patch updates. I don't want any big companies to buy Ubuntu. An independent community driven Ubuntu is stronger than IBM's, HP's, Novel's or Oracle's Ubuntu. And did I mention it has the coolest name?
