Disagree with Curtis, it's actually possible to automate this so it doesn't take him spending weeks reading up on flatware. Just use the knowledge of those who already have. My startup's app analyzes user ratings and tells you immediately which one's good for your purposes. Give it a shot: http://tryarrow.com.
I would far prefer to use that "app" as a website, not as a phone app. I have approximately never been walking around with just my iPhone and thought "Oh! I want to buy a new Point and Shoot Camera! Let me enumerate my preferences..."
As a website, I'd seriously consider using it, particularly for stuff (like flatware, or shoes, or dish soap, or whatever) that I don't care that much about.
Sure, that's the way we research things today, but once it's in your pocket and it works, it'll happen on-the-fly. Just like how nobody sits at a desktop and prints out maps today. Also I use my iPhone for everything these days.
We actually threw up a web test and it got way less interest than the mobile version, probably because it was less novel on the web (other sites existed, though they didn't work).
