For me, it's all about pixel density. I have 20/10 vision..I can CLEARLY see the pixels. It's utterly horrid..
I'm at 20/15 w-o correction, and I can see the pixels in my EVF too if I want to concentrate on that. But it doesn't bother me since I don't expect it to look exactly like an OVF. There's enough information density to be useful for what it is, a composition tool with a rich amount of camera data added. I don't need to color-proof with it, don't care if it has other limitations you've described, as long as it's fast, responsive, works well in low light and provides the information I need to perform the function it's supposed to.
It does that just fine, and it's even better than an OVF when it comes to low light. I don't mind a little noise in my low light EVF image when it allows me to see more detail than I could looking thru an OVF.
So, if today's EVFs don't appeal to you, tomorrow's might.
One of the other benefits is I get from an EVF is a much better idea of how a stopped down image will look because I'm seeing it without the effect of a focus screen in an OVF that interferes with how the image actually looks for in-focus to OOF transition areas.
Either way, good EVFs won't prevent you from using them for what they are there for, to compose the shot. Even the very low rez EVF in my old Panasonic FZ-20 was useful and still truckloads better than trying to compose using the rear display in sunlight.
