Here is a cool tool from Coldwell Banker to aide you in your home search:
Coldwell Banker® Personal Retriever service is also available as a Widget - a small application that can search for property listings in the price range and area you're interested in, and deliver them directly to your desktop. It will even alert you when there are new listings.
"What are Widgets" you ask? They're small, mini-applications that perform specific tasks and run in the background on your desktop. There are Widgets for weather forecasts, stock trackers, calculators, sports scores - and now you can get a Widget for your real estate needs.
