Back then, did we have an app that can do email and calendar, and sync that with our phone?

Did that app work on all operating systems that were in use at that time? With a simple install? On DOS, Amiga, Apple, Acorn, Unix? The same app, with the same functionality?

If not: Would you rather live in a world dominated by native Windows applications, written in C with Win32?

Yes, when the phones were based on Blackberry, Symbian, Windows CE / Pocket PC.

Naturally before that there where no phones with Email to worry about.

There were games available across all those platforms, which are a specific kind of apps.

Wordperfect is good example of something available all over the place during the 1980-90's.

Thankfully C isn't the only way to use Win32, as it was already not the case with Win16.

Which cross-platform email+calendar GUI app existed back then, which could sync with these phones, and works with feature-partity on all of Windows, Mac and Linux, and was not built with web technologies?
