actually I think it is useful but not critical.
I thought waist height pictures are quite nice and I find myself kneeling on numerous occasions.
I think it will be MUCH better than zigview... it for one uses a SEPERATE 8 MEG CCD to do the live feed. Supposedly the same CCD as the one found in oly 8M P&S.
But I think oly got the pricing all wrong as this DSLR will be priced above entry level ones.... If only it competes at the entry level DSLR, it could be a big factor for P&S upgraders. P&S upgraders usually buy entry level DSLRs...
