Ooh, I'm sure the wine experts on the board may have a comment on this, while I agree with some of the points may be partially valid, my 6 year old can tell a white from a red wine blindfolded just by smell alone. My wife and I always get wines we enjoy by taste rather than price, but even I of no profound wine knowledge will choke on a 2 buck chuck in a blind tasting. My wife who is much beter can 90% of the time distinguish the type of fruit and flavors in a wine by smell. That doesn't mean she will pick a $100.00 bottle over the black box as her preffered choice for taste though.
