Fonts render at whatever size you tell them to. That doesn't change.

I have the Viture not the Xreals, but anyways... my experience:

I do find that there's significant optical aberration that makes text more blurry towards the edges. I also have astigmatism; not a deal-breaker but it means the built-in myopia adjustment only partially corrects my vision. I basically got contacts again just so I can use these a bit better. But it still feels less clear than a regular screen with glasses or contacts. Doable but not great for text.

I don't know about Viture, but the XReals come with a prescription lens attachment clip. I've got a set. It would be unusable without it, but even then the screen is only really great towards the middle of the field.

In theory the hardware has a motion tracker that lets you freeze the screen in space and pan around it by moving your head, which would be a huge win, but the current iteration needs an external dongle to do that which I don't have.

I'm going to upgrade to the next version purely because that's going to be built in (along with some other niceties).

This Steam Brick is right up my alley, although I'm wondering if you could do something just as slick with Framework guts. I haven't fired up Steam in a while.

Frame.work has a cooler master case:

I have my old mainboard chugging along in one of those, works alright. Wish the fan was less whiney though.

It’s basically like working on a projector. Everything is just a bit too hard to read.
