Were all disappointing or outright failures, right?
Every product you just named were from Apple's distant past and were markedly different from the Vision Pro. These are all products that were made for already established markets and not trying to create a new industry. The Lisa for example was overpriced for what it could do but was still a desktop computer in a time where everyone had and wanted desktop computers. Mobile.me is iCloud before the name change. It had a rough start but very much still exists today. Virtually no one outside of serious gamers are looking to buy VR/AR headsets. Until Apple can clearly define a use case it will be a long time before it becomes viable.
