I sell appliances too at Sears, and I fail to see how this is anything more than a gimick. I don't get how you would use that at all? Are you going hand the customer your phone so they can look at reviews, specs, dimensions, etc...
The only time I use the internet at work is if we are going to price match or if they want something I don't have a display model of.
Please explain how you are using this.
When every Tom, Dick and Jane has a bar code scanner on their phones (feature phones too), people will look back and think, "damn, wish I had jumped on this when Lowes did."
Its getting more popular all the time. Backwards thinking of the above sort does not fuel innovation.
