Well for every feature request, an example of 'absolute necessity' can be dug up. That's nothing new. It still doesn't render the current viewfinder 'of not much use' in bright sunlight, certainly not in general terms. But as you're asking for an education, I will gladly point out the available folding sun screens, cheap&useful and hardly adding bulk to the camera.

Also, you need to "educate" Sony because they disagree with you and put an EVF on all their higher level cams. It is so annoying when your brand of choice disagrees with you.

If they decide that a model or models is above the current level then they will add an EVF like they do in their other products.
I can't say I follow that reasoning. NEX-photo is clearly a product line that has an emphasis on portability, simplicity and price and an EVF would infringe on those 3 core points. Also, I'm not sure you can compare the video market (as I assume you are doing) with the photo market. People who desire perfect viewfinders, can buy an SLR. An EVF on NEX would cannibalize Sony's own SLR range, which I guess, looking at the competition, needs all the momentum it can muster.
I expect there will continue to be the lower end NEX bodies that don't have an EVF, just as Sony's lower end videocams don't have an EVF.
Well, you could be right of course. If sony decides to develop NEX into a fully fledged range, it could be true. If they decide to keep it, as it is now, somewhat distinct from ther SLR market, I again don't see that immediate parellel to the video market.
As an alternative to reading glasses, I use a low power jewlers loupe that fits in my eye socket attached to a thin neck cord. So I can quickly pop it in my eye, make focus then it just falls away safely. Easier than putting glasses on and off so often. I carry this loupe discretely (discreetly?) under my shirt nearly everywhere I go--it's handy for everything and better for Nex LCD focus than glasses.
I'd been thinking of that as well, thanks for reminding me

After all, glasses are not-very-handy things to stuff into pants' pockets.
I kinda like the idea of an old Rolleiflex-style sun screen and an 18th century monocle combining to be used on a modern camera
