Inconsistent? I feel the opposite. Right now, every app seems to have its own UI design. Back then, most apps were native Win32: maybe ugly, maybe too serious, somewhat limiting, but mostly consistent. And relatively fast, despite running out of a spinning HDD and a single-core CPU.

Well, it was a mix. Win32, then the Lotus family just refused to conform.

And some others. IP? No, we are a NetWare IPX network!!
