A new gadget called the Xenote iTag is a clever marketing device for radio stations and CD merchants. It looks like a car alarm remote, but cooler. When you hear a song on the radio that you want to identify later (assuming you’re listening to the station you got the iTag from), you hit the button and it “bookmarks” the song. Later, you hook it up to your computer, upload the tag and get a listing of what songs you’ve bookmarked, complete, of course, with handy links to purchase the CDs. Candace Murphy at the Mercury News is enraptured, calling it “the coolest invention on the planet”. I was skeptical (consumerism, ack!) as I read through how Xenote wants to enable this technology for “bookmarking” products you see and places you go, until I remembered that I use my PalmPilot mostly as an electronic shopping list. When I see or think of things I want to buy, I jot them down with HandyShopper for my next trip to the mall, bookstore, CD store, supermarket, etc. Maybe an instant bookmarker device, with UPC code scanning, would enhance my shopping list capabilities.
