If anything, focusing based on the digital image should be MORE precise because you are viewing the image that is falling on the sensor, and not an approximation bounced of a mirror and onto a focusing screen...one of my SLR cameras is out of whack and you have to focus slightly front of your intended target in order to actually be focused properly on the film, due to slight path-length differences between the focusing screen and the film. You only notice this in, say, macro photography with large apertures.
I don't know why you keep talking about 'optical viewfinder' is unnecessary in DSRLs. I'm actually not quite sure what goes on in your mind, this is borderline absurdity you're talking about here.
Let me tell you why DSLR still has an optical viewfinder:
1. LCDs DRAIN battery. Especially if you have a huge 3" ones. That's why most people prefer to compose using optical viewfinder. One of the main selling points of DSLRs over compact digital P&S is that you can take much much more shots compared to P&S. If you want to use an EVF to compose, get a Kodak Easyshare, not a DSLR, simple as that.
2. Now I don't know about your handholding technique, but have you actually tried to use a large DSLR with large lens, composing and taking the shot solely using the back LCD?
Either you have hands of steel, or have no clue what you are talking about. For most people, using your optical viewfinder and holding it against your face gives you extra stability. Using your optical viewfinder will match your elbow position, feet position, etc... this is a basic photography 101 we're talking about here.
Especially if your camera is something as large as D300, with a lens as large and heavy as 17-35mm (this is a very common combination), combined with a flash unit on top, now you are telling me that you'd rather have your camera without optical viewfinder and prefer to shoot like you're holding a digital P&S instead? Rubbish.
3. I know that DSLRs even the high end ones still don't have viewfinders as good as the likes of Nikon F6, but have you actually tried one? Go to a shop and look at the viewfinder from D300, and if you tell me that's not good enough for you to make decent shots, maybe you should take up another hobby.
4. Have you tried looking at LCD screen under bright daylight? If you camera didn't have an optical viewfinder and the light was too bright the LCD was washed out, what would you do then? Stop shooting and go home?
But then again, if you are so persistently anti DSLR, that's your loss, not mine. I'd rather help other people with their camera query or work with my DSLR than debating about this kind of stuff. Please don't tell me you're also anti post processing.
