Google has added a cool feature to Google Product search that allows you to scan a barcode with Barcode Scanner and it will automatically search for the product on Google Product Search. Similar to the apps ShopSavvy and Compare Everywhere, but a different interface, and presumably different results.
To get started, you will need to install Barcode Scanner from the Android Market, then just open Google Product Search and click on Scan Barcode:
This will not completely render the other applications useless. I still prefer the interface of ShopSavvy and the local results using GPS. Although it’s quite possible Google can integrate those features into Product Search.
