Today is Tom Selleck's birthday. On TV he played Magnum P.I and spent lots of time investigating things. If he's looking for new appliances for Master Robin Cook's mansion, he and Higgins won't have to leave their palatial island estate at all. They can skip reading magazines and looking in the Yellow Pages for the names and numbers of Hawaii's biggest and best appliance dealers. With a cold mai-tai in hand, he'll be surfing instead, surfing the net -- investigating Web sites of the big five U.S. appliance manufactures -- GE, Amana, Maytag, Whirlpool, and Frigidaire -- to see what's new and to compare. Then pouring himself another, he'll cruise the European manufacturers and trendy little boutique companies and those who make upscale ritzy primo equipment. When he's all done, in about an hour or so, he'll settle back with another cool one and drift off thinking about his all-new, no-hassle dream kitchen. You can, too, just log on. Aloha! And that's the On the House tip for today.
