Zune never took off just like HoloLens, Band, Kinect and Windows Phone didn't take off—not because they were in any way late, but because Microsoft is never "all-in" with any of these ventures.
The Xbox was somewhat of an anomaly owing to exclusives like Halo and Gears of War, but it's floundering, and in some countries, like Japan, it's just never taken off, period.
Apple Vision doesn't seem to be a sensation in terms of sales figures, despite the HoloLens beating Apple to the punch, and the stereotypical nonsense being "Apple is always late, but they always do it right". HoloLens just got killed along with Windows Mixed Reality.
Hell, even the Microsoft Band beat the Apple Watch to market.
The problem is that merely having a presence in a niche doesn't guarantee success as it once did. Now, you need to actually iterate, innovate, and satisfy the minimum expected threshold of solving real problems. This is also what Tim Cook's Apple struggles with these days.
What's the killer app for Apple Vision? What was it for HoloLens?
When digital technology was new and exciting, having anything would draw buyers. Now, we're spoiled for choice, things move fast, it isn't years between models, it's months to a year. Early adopters tend to get a bad experience too.
