I had and loved a similar NEC CRT. But 2048x1536 on a 22" display is ~116ppi. Apple's non-retina laptops have been higher than that for years (with the MacBook Air being highest, at ~135ppi), and Sony, at least, has offered configurable 1080p displays in 13" laptops (~165ppi) for some time.
It was pretty nice a decade ago, when everyone was moving to LCD monitors that were vastly inferior in every measure beyond size or weight, but, at least in terms of ppi (and on consumer grade equipment), display technology eclipsed the CRT quite a while ago.
edit: I'd forgotten that CRTs were measured with the bezel included, so at 20" viewable, the display is 128ppi. So closer, but still pretty far behind.
