When HP unveils its PalmPad tablet at CES 2011, it'll fight the iPad with front and back cameras, a speedy USB 3.0 port, and a mini HDMI video output. Plus, it's rumored to be 20 percent lighter that Apple's gizmo.

According to sources who spoke exclusively to FoxNews.com, CES 2011 will see HP formally announce its tablet initiative. Dubbed the PalmPad and built around the webOS operating system, the lineup will actually consist of four different products targeting consumer and education markets. The publication claims to have obtained an exclusive drawing, seen above, that allegedly represents the design of the real thing.

The first three versions for consumers are said to be a "spin-off" of the ill-fated HP Slate that got nixed over short battery life and poor performance blamed on Windows 7's resource consumption. Those three SKUs will all run webOS version 2.5.1, support Sprints fast 4G network, and sport minor hardware differences distinguishing them.'

According to author Clayton Morris, a fourth version is being described as tailored for the educational market. It should carry an 8.9-inch display, but HP won't show off this device at CES 2011:

A fourth version won't be shown off at CES, I’m told, but it will be custom made for university students to prove how versatile the machines can be.

Compared to Apple's iPad, the three PalmPads made for consumers will all feature a 9.7-inch display, like the iPad. Note: The image you see on the left is a mockup, not the actual pre-production unit.

These devices are purported to pack in a mini HDMI port and sport a slightly thinner appearance than the iPad, with "rounded edges closer to the Amazon Kindle".

In addition, they will have a forward-facing 1.3-megapixel camera for videoconferencing and a three-megapixel camera on the back. Both cameras should utilize LED flashes. All three units will weigh in at 1.25 lbs each, making them at least 20 percent lighter than both WiFi iPad (1.5 lbs) or WiFi+3G iPad (1.6 lbs).
