Don’t look for Hewlett-Packard Co to enter the $500 Network Computer market – unless it takes off like a rocket of course. Speaking in Mexico City, chief executive Lewis Platt averred that We won’t enter the low-end market because its margins are slim, and we believe it won’t last more than three years as consumers will begin to search for higher-capability products. Dow Jones & Co quotes him saying Hewlett will only watch this market from the sidelines – since it will be easy to enter, a variety of companies will come in, and ease of entry means that Hewlett can always change its mind if necessary.
