For those who don't read the techie consumer fan sites like EnGadget.com the G1 is sorta like T-Mobile's answer to the iPhone but with a major twist. Its Android operating system "engine" was built by Google which means that there's a terrific bundling of Google's suite of killer apps on the phone. This isn't intended as a review of the G1. There are tons of those on the web, including an excellent overview here.
This is about one of the many unique features on this phone which only the crazy kids at Google could have built, Shop Savvy, and which could save you a bundle with your home improvement purchasing. Shop Savvy lets you do real time price comparison shopping while you're on the road.
