Yeah, I'm still not sold that the move from the mainframe model was the correct one.
I watched an AS/400 (technically i-series by the end) run through various platform iterations for around fifteen years before being replaced with other solutions, and in the five years I watched them struggle with those other solutions for finance, payroll, timekeeping, and other back-end business functions, that AS/400 just did those without a whole lot of fuss. Sure, it meant that users had to get in via terminal emulator and to tab-through fields to do their data entry, but those clerical staff that had the capability to learn how to do that were really goddamn fast when it came to doing data entry and records retrieval.
Every post-AS/400 solution required mousing through multiple menus and waiting for retrieval and rendering of pages. Things took ten times as long, and were arguably even worse than experiments with HTML rendering for AS/400 forms to try to bring them into the modern-ish era.
