I think you'll be amazed by how much more accurate your focus is with 10X live view than any other method (autofocus, OVF, anything). The problem, right now, is the handheld ergonomics. Holding the camera out in front of your face to see the LCD like a neophyte digicam user is not very fun. That's why video shooters like me invest in a big shoulder-mount rig, which does great double duty for stills shooting with live view:

Actually, it's because of the design of the viewfinder screen. The standard screens don't scatter enough light to see accurate DOF past f/3.5 -- they're more on the side of an aerial image. There are optional screens available (and ground glass screens from third parties like Katz Eye) that scatter much more of the image, giving you far more accurate DOF. The downside is that the viewfinder becomes much darker. Some people find the Eg-S unusable at f/4 because it's too dark (personally, I find it usable. I even use f/5.6 by letting my eyes adjust).

I would *love* negative shutter lag. It would let me overcome my own delay. Say the camera takes 65ms, but my human reaction is so slow that I take 300 ms. The combined time is 365ms. If I set the shutter lag to negative (-365ms), then it cancels out my slow reaction time. I would have to measure how slow my reaction time is, of course.
