It's crazy too to realise how much of the multi-application interop vision was realized in Office 97 too. Visual Basic for Applications had rich hooks into all the apps, you could make macros and scripts and embed them into documents, you could embed documents into each other.

It's really astonishing how full-featured it all was, and it was running on those Pentium machines that had a "turbo" button to switch between 33 and 66 MHz and just a few MBs of RAM.
