Other all-in-one PCs of similar size are going to launch with single-core Atom microprocessors.Asustek’s Eee Top, for example, is also a 15.6-inch all-in-one device but comes with just a single-core Atom microprocessor as well as a nearly identical price tag of around $600. Micro-Star International (MSI), which plans to launch a family of all-in-one PCs under the NetOn name, will also market a 15.6-inch-screen device with the single-core Atom, the NetOn AE1600, though pricing information was not immediately available.The company will sell a few larger NetOn all-in-ones with dual core Atom microprocessors, including the AE1901, which has a 19-inch screen and the AE2203, but again, pricing was not available.Shuttle’s X50 is aimed for use as digital signs or in stores for informational purposes. The device uses an Intel chip set with Graphics Media Accelerator 950 integrated graphics as well as an 80GB HDD (hard disk drive) and a 1.3-megapixel Web cam.A number of companies have been selling desktop monitors that have computers built in, including Apple’s iMac, Dell’s XPS One, and Hewlett-Packard’s Touchsmart PCs. These devices carry far more powerful microprocessors and other parts than the Intel Atom-based devices described above, as well as heftier price tags.All-in-one computers have become popular as space-saving devices on desks.
