Resolution is roughly around 1800x1920 over 100° FOV. That means you get around 19 pixel-per-degree. Retina resolution is 60 pixel-per-degree. Acceptable text readability starts at around 30 pixel-per-degree. So no, for most common uses this is nowhere near good enough. It's like having an old 720p LCD TV on your desk. It works for casual web browsing and movies, but far away from the image quality of a modern 4k monitor. Nreal Air at around 49 pixel-per-degree is the closest thing to a monitor-replacement you can currently find, even has a plain HDMI input. Does however come with a lot of other short comings (no 6DOF tracking, monitor image not tracked, low FOV).
