nice writing and all, but sir you have no first hand clue about corporations. not everybody is using new cool toys of the day as backbone of their whole company. For example i work at the bank, the whole core banking package is basically app build in pl/sql on top of oracle db. i like cool new technologies, but to even think they would run in next 20 years anything else than their super-cluster is funny and ridiculous, and... stupid. Some non-critical apps like HR, timesheets and whatnot? Sure, have it in SAP (why isn't anybody discussing this super massive pile of crap? compared to that, oracle's offerings are slick cool lean easy-to-use tiny gadgets). Or some MS/IBM solutions.

Let's not forget quality support cost a fortune, and that quality part is more important than some numbers on budgeting spreadsheet. Bear in mind, these static part of IT budget are carved in stone, nobody is questioning them.
