I encountered those ads several times during the long, cold, wet, winter, and tried to picture myself standing in the snow to receive a wireless ad. So far, wireless shopping has also failed to make its case with the consuming public. Nothing about it really solves the problems already miring online shopping. You use a smaller, more mobile device. So, you're really just doing the Internet thing, except on a smaller screen.
Some decent ideas are out there.
Starbucks, for example, has teamed up with Microsoft to bring wireless Internet connections to its coffee shops. While sipping your latte, you'll be able to read, via wireless, the latest in entertainment news, shopping info, and local goings-on. It marries the information benefits of the Internet with the ambiance and caffeine rush of the Starbucks experience. But the smart proposals are few and far between. It's not that I don't want wireless to work.
