Well I for one tend to think if it ain't broke... I'd mostly (say 75% of the time) use such a camera with a 35mm (equivalent) lens, and would expect the OVF to be brighter and clearer for careful framing (not always necessary) than using the rear screen. For the remaining 25% (maybe 50/50 21/25mm equivalent and 90/100mm equivalent) I could make do with the screen.

I remain highly interested/optimistic about this little Oly, whereas for me the G1 offers so little size/weight saving over a normal SLR that its reliance on an EVF totally outweighs its (debatable) advantages.
