| That's a fair bit higher than a Quest 2. That might be enough for
| productivity based on my own subjective tests.
|
| I hope they succeed. There's a lot of potential.

| I've come to the conclusion that this is the factor holding

| feels kind of flat and small. Hard to describe.

| Similar to curved monitors...

|
| I have been really impressed with the hardware though. Games

|
| I want it to be my multi-monitor setup but it's just not quite
| doing it for me yet.
