Taiwan computer maker Asus might have underestimated the local demand for its diminutive Eee PC, as the $499 laptop is now virtually sold out in Australia.

Neither Asus nor the exclusive retailer, Myer, will say how many units were sold, but an Asus spokeswoman said more stock would be shipped to Myer at the end of this week.

The Eee PC, Australia's cheapest laptop, went on sale in Myer stores nationwide on Sunday and by close of business on Monday all the capital city stores were sold out. The Asus spokeswoman said other metro stores might have a small amount of stock left.
