Hewlett-Packard (HP), Asustek Computer and other vendors plan to develop 15- to 17-inch AIO (all-in-one) PCs in a bid to tap the low-cost segment, but this will decrease demand for large-size notebooks, according to Taiwan-based supply chain makers.

　　Currently, more than 70% of AIO PCs are 21- to 23-inch models, with 23-inch being the mainstream screen size, the sources indicated.

　　While AIO PCs are expected to replace desktops, AIO sales has so far been short of expectations, the sources noted.

　　HP has adjusted its AIO PC supply chain by increasing the proportion of ODM orders to Foxconn Electronics and decreasing those to Quanta Computer, Wistron and Pegatron, the sources said. With AIO PCs selling at an average price of US$600, HP ships 2-2.5 million AIO PCs a year and is globally the third largest vendor next to Apple and Lenovo, the sources indicated.

　　In order to lower AIO PC prices, some vendors including HP and Samsung Electronics plan to launch Chrome OS-based models, the sources indicated.
