XP, LAMP, 2003 servers, all of those things are spiffy new systems to us. Almost all of my job is trying to get old PDP, MODCOMP and DOS systems into the modern era of things like Windows NT or (Jobs forbid!) linux. Sites with truly aging systems are rarely willing to spend anything like what it would cost to really bring what they have up-to-date and they often have good reasons -- how many security issues do you hear about those aged systems vs [recently] modernized ones?
Of course, it also help to keep all user interfaces the same as much as possible instead of forcing people to learn something new (are you listening, Microsoft?) That kind of change for its own sake rarely adds value. I've seen really great looking Windows software used on the operators' console at nuclear power plants -- except -- it is only great looking from a couple feet away. If you get farther away the lines being graphed become invisible and the text is too small to read without 20/10 vision. This stuff probably only changed format because some programmer (and marketeer and purchasing agent) thought it looked pretty in demonstrations in a conference room.
Ahem. Sorry, poor human factors in software "upgrades" is a pet peeve of mine.
