Dell's hybrid XPS 18 is a $900 all-in-one PC that turns into an 18-inch tablet

Dell is pulling back the curtain on the XPS 18, its new portable all-in-one. This machine is a natural competitor to the Sony VAIO Tap 20, with a built-in battery (rated for five hours of runtime) and a similar design that can transition between traditional desktop mode and lying flat — in this case, thanks to flip-out feet on the rear side of the device. With an 18.4-inch, 1080p display, the 4.85-pound XPS 18 makes for a pretty enormous tablet, but we’re talking portable in the sense that it can tag along on business trips and move from office to living room every once and a while. The all-in-one will come with a Bluetooth keyboard and mouse when it debuts in April, and a $50 dock will be an optional accessory. Pricing starts at $900 for a dual-core Pentium ULV and a 320GB hard drive, and the top-of-the-line configuration will offer a Core i7 CPU, 8GB of RAM and a 512GB SSD.
