That's because the "fully featured" of the 90s would be barely usable today. Or to rephrase: the frameworks and programs of today are not "similarly powerful" to the ones from the mid 90s, even if you just recompiled the app from 25 years ago with the current version of your framework (theoretically ;), it would gain support for unicode (codepages where just...), internationalization, accessability, support for networks (who still knows Novell?),... . Except for SAP, they somehow succeeded at combining the user-hostileness of the 90's UIs with the resource consumption of contemporary programs ;).
Turbo Pascal had been the language I used after BASIC, with which I started.
