ROBERT O PUTNAM ,e.DIGITAL senior vice president ,shrugged when asked if the company is worth $2 billion or $3 billion .But he pointed out that in the era of RED-HOT-DOT.COM stocks , there are plenty of unprofitable companies with multibillion-dollar stock values. PUTNAM said e.DIGITAL is certainly in a much stronger position than it was in the days when the stock traded for 5 cents a share. But the real money would be in the MICRO-OS technology , which PUTNAM said could eventually go into other devices in addition to music players. " IF WE ARE SUCCESSFUL IN MAKING MICRO -OS A STANDARD OUT THERE , THAT PUT US ON THE MAP FOR YEARS TO COME , " PUTNAM said.
