Cool.

My immediate thought when filling out a new listing...

You should auto complete. For anything and everything (that you can.)

I type in Xbox.. a list drops down with xbox 360, complete with Photo, MSRP, estimated value (based on other data points ie craigslist or ebay) and a pre filled out description.

Well, sort of like what ebay does I guess. I hate filling out forms. Everyone else does too.
