Seems like a lot of comments here are US centric. As if Canonical and Suse don't exist and aren't Europe based/focused?

Also a lot of arguments that MS provides some total package which is irreplaceable which just isn't true. That argument seems to conflate software dominance in the US (is that even true? Linux runs most back end) with some kind of hardware dominance. MS doesn't provide hardware beyond some limited set of desktop hardware which most businesses don't even use. Most business lease from the likes of Dell, HP, and Lenovo both front and back end. This should probably be the real discussion.
