ASUS has had a hard time meeting demand for its Eee Pad Transformer since the device's launch earlier this year. Jerry Shen, the Taiwanese company's CEO, says that he expects to sell 300,000 of the tablets this month, following shipments totaling 400,000 in April and May. That figure puts the device in the number two spot for worldwide tablet shipments, just behind the prevailing iPad 2. At that rate, ASUS's latest hybrid will bring in NT $2.5-3 billion (approximately $86.6-104 million), accounting for 10 percent of the company's total revenue for June -- a figure which could increase after sales pick up in Europe and mainland China in Q3. As for North America, it looks like e-tailers are finally able to maintain inventory of the $399 (16GB) flavor -- it's listed as in stock with major sites, including Amazon and Best Buy.
