>>When I started working with PCs in corporations I worked in several places where there was an old guy sitting in the corner that no one hardly ever talked to. His job was to maintain some mainframe code. I knew then that I would never be comfortable ending up like him.

Cute story, but more like something you picked from a "Dilbert" cartoon ...

Your implication is that people only "maintain" mainframe code; that there is no "new" development ... In which case, you are wrong.

Mainframes are still being installed; you just don't read about it because they are not featured in your Wal-Mart flyer ...
