It had less features too.

Now, I do agree doing more doesn't mean that something is necessarily better... but I think the UX difficulty increases exponentially as more features are added.

Absolutely, and in my opinion it's a mistake to keep adding features. My word processor in the 90s did one thing, and it was fine. In fact, there's a niche crowd trying to re-create that experience right now (distraction-free "writerdecks"). All software used to be like that, and I for one was a lot happier with the situation.
