Unfortunately I haven't tried that one! $6,500 is a bit out of my personal price range haha and I didn't get a chance to try all the competitors while I was at Apple.
I'm not saying 3500 is "alright", it's definitely still expensive!
I would say 6500 is too much for a better version of something I already have that doesn't really enable any additional usecases. The Vision Pro would be used pretty differently than my Vive (which is just the occasional gaming session right now). I'd think of it as more competing with iPads, external monitors, and laptops than a Varjo right now.
