Increasingly bigger smartphones are no surprise anymore, but Dell just unveiled an insanely huge 18-inch, super-thin tablet/ AIO called the Dell XPS 18.

At 18 inches the XPS 18 can hardly go as a tablet, but rather an AIO PC. The device will make its debut on April 16 in the U.S., with a starting price of $899.99. It will sport a whopping 18.4-inch capacitive touch Full HD display (nearly twice the size of the iPad's), but an overall weight of just 4.85 pounds. In other words, the device is either a crazy huge tablet or a super-light AIO.

"It features much of the power you would expect from an AIO while still being surprisingly portable, so you can use it in many different rooms in the house," explains Dell's Lionel Menchaca. "It works well as a streaming media device in the living room, viewing recipes or cooking videos in the kitchen, or as a homework machine in the kids' room."

The company did not reveal much in terms of specs, but the Dell XPS 18 will come with a Bluetooth mouse and keyboard, as well as custom flip-out feet to turn the device from a tablet into a desktop.

The basic model will include a dual-core Pentium ULV processor and a 320GB hard disk drive (HDD). Higher-end models will reportedly include a third-generation Intel Core i7 CPU, 8GB of RAM and a 512GB SSD. The battery will last for roughly five hours on a single charge.

"It features an aluminum back with soft grip for traction and comfort," adds Menchaca. "Overall craftsmanship and flexibility were two key focuses for our design team. You can use it in a number of ways: on an adjustable powered stand so it can be used with a wireless keyboard and mouse, on a desk or surface with flip-out feet so it can be set to a comfortable viewing angle, totally flat for collaborating or browsing, or even like a newspaper for reading."

The Dell XPS 18 is listed as coming soon, and will use Microsoft's latest Windows 8 operating system. The hybrid will also include the Dell Wyse PocketCloud application to enable users to build and manage their own personal "cloud." According to Menchaca, users can share these files to other iOS and Android devices.
