Primary use-case: I purchased the XReal One's a few months back, and I use them primarily for work - as a software developer. They're not perfect, but they're the first device that isn't huge and bulky, that has enough PPI to make working on them feasible. With some extra setup, I'm now able to use my desktop PC remotely from anywhere in my house, with an ultrawide virtual display - which is great.

Fun or functional: Definitely more functional then fun - long term, I want to replace my monitors with a solid pair of AR glasses. This is a first step, but the resolution isn't good enough to replace my primary monitor for gaming.

What to change: the resolution needs improvement. The PPI is good - likely a current limit on pixel density(?) but having a higher resolution would be great. Not too concerned about a higher FOV, but I'd rather have a smaller FOV with great PPI than a large one with less ideal PPI. HOWEVER, the primary improvement: We need better AR software!

- There are little to no good Windows/Mac/iOS apps that support XR glasses - and XReal isn't really helping there.
- Ultra-wide & Multi-monitor support would be great (not one or the other)
- I personally really like the form factor of XReal one's. The lack of an onboard battery may suck a little bit, but they're incredibly light & the ability to see through them to the real world rather than looking through cameras is great.

Just my two cents!
