the economy situation is probably playing a big role in this too. also if something is running fine why change it, for example still many of the banks and airplines use IBM OS/390 operating system that's over 50 years old, with a DOS like interface, but it works for them so why change it... also many banks still run OS/2 on some of the PC Servers, which is an exctint OS lol, never the less it does what it's suppose to, so they keep it running...
