I disagree on the watches but agree on VR. A phone in your pocket is really absurd when you think about it. It would be far more useful on your wrist for 80% of what you'd use it for. For the remaining 20% (gaming, typing longer texts, etc.) you can still have a larger phone but it would mostly stay in your bag.

As for VR, there is a solid 30+ years of it being "the next" thing and then failing to be. I tried the Oculus recently and it didn't change my mind.
