Well, I guess this whole argument about crop vs. focus comes down to the style of shooting that you do.
If you are shooting wildlife, sports, events etc., then it is almost a requirement to use a long fast lens. If that's your style of shooting, more power to you when you crop, because I'd rather see an inspiring final product than be distracted by useless elements in the photo. I can see why Leon (as well as countless others) would want a VF with better focusing properties. That being said, the VF has absolutely nothing to do with AF (as far as I know in the Canon AF system), so I will assume that you MF. Then, my sincerest kudos to you for having mad MF skills.
For the others who have a different style of photography and have large printing implications, every single pixel is important. Not to mention expensive. So some of us take the necessary time and precautions to avoid cropping, including properly leveling the camera and meticulously framing the subject. It's not as though we don't take multiple photos of the same subject, just different compositions, all of which we hope to yield good product.
SO, why can't Canon give us a higher magnification value (and thus bigger VF), a brighter VF and a 100% view in the same package? (It's a rhetorical question people )
In the end, it looks like everyone wants from the VF what they need to get the picture they want.
