A day before the CES show is set to kick off, Asus confirmed swirling rumors by formally announcing four Eee-branded tablets. Three are based on Google’s Android software while a fourth runs Windows 7. The Android slates are of particular interest because they run Android 3.0 codenamed Honeycomb, the latest and greatest Android version specifically created with the tablets in mind. Regardless of the operating system, however, all four devices come with interesting twists, like integrated keyboards or the dreaded stylus-based input that we thought died in the 1990s. Here’s a quick overview of all four devices in no particular order.

Eee Pad Slider

This Android slate trumps the iPad in screen size, 10.1 inch versus 9.7 inch on Apple’s tablet. It’ll sport front and back cameras for taking pictures and videoconferencing. The Eee Pad Slider, as the name suggests, will include a full fold-away QWERTY keyboard for prolonged text entry that turns it into a mini-notebook.

It’ll be capable of 1080p video playback via Nvidia’s Tegra 2 chipset and will support WiFi and Bluetooth connectivity.

Eee Slate EP121

This pricey device will run Microsoft’s Windows 7 on a twelve-inch WSVGA 1280×800 touchscreen. Remembering HP’s sluggish Windows 7 slate, how do we know that this thing will run fast without draining battery? Well, for starters, the Eee Slate EP121 will be powered by an ultra-low-voltage Intel Core i5-470UM processor that provides notebook-class power while conserving power.

Coupled with an option between 32GB or 64GB solid-state drive, this should give you enough oomph to run desktop-class software. WiFi and Bluetooth connectivity, a two-megapixel camera for taking photos, a mini-HDMI video output and wireless keyboard and stylus support round up the list of features.

Eee Pad MeMO

This seven-inch tablet will offer HSDPa+ cellular connectivity via what’s called MeMIC, a Bluetooth media phone extender that will let you make calls and send and receive text messages. Other than that, this dual-camera Android device also packs in in-plane switching display like on the iPad, allowing for wide viewing angles.

It also beats Apple’s gizmo with a USB port, microSD card slot for storing music and photos. Oh, and it comes with stylus that works in conjunction with note-taking and photo-editing apps.

Eee Pad Transformer

This 10.1-inch Android 3.0 tablet runs Nvidia’s dual-core Tegra 2 chip and packs in front and back cameras, HDMI video output and claims at least eight hours of battery life. What’s interesting about this device, besides the catch name, is that it works in two modes: The pad mode and docking mode.

The Pad mode lets you use the Eee Pad Transformer as a regular tablet. The docking mode allows you to dock the device to a keyboard dock which has a clickpad. This mode essentially turns the Eee Pad Transformer into a mini computer.
