I guess I'd say it this way... there was a very simple case for Windows 95 that allowed for a big launch. The innovations were obvious, and the product was clearly superior to what it was replacing (Windows 3.x).

As a thought experiment, how would you even do a big launch for Windows 10 or the latest MacOS? I like both products quite a bit, but I'm not even sure what you would launch? A big pile of marginally useful features?
