Excel 97 -- How Dare You!
The problem with Excel 97 -- in fact the entire Office 97 suite -- is that it actually works rather well. The only way to improve it is to do what everyone does these days which is to repackage, bloat and kill off compatibility. In real life software doesn't wear out, unlike physical equipment, so if a program's doing a job then it can continue to do that job indefinitely. (Computers don't need to be connected to the 'net for many functions)(although much modern software demands it 'for business reasons').
(Since I work with 'real' computers, including doing odd bits of scripting, I find the Lego Mindstorms approach to writing software for IFTTT needlessly verbose and unduly restrictive. After all, IFTTT is just a subset of if/then/else, an everyday construct in all procedural languages.)
