LAS VEGAS – Asus on Tuesday unveiled a series of new Eee-brand tablet devices, including two Honeycomb tablets, a Windows-based option, and an Android smartphone dubbed the MeMO.

The Eee Pad Transformer and Eee Pad Slider are the Android tablets options, while the Eee Slate will run Windows. The Eee Pad MeMO, meanwhile, is also an Android device, running on a Qualcomm Snapdragon processor.

The Eee Pad Transformer is an Android 3.0 Honeycomb tablet with a 10.1-inch, 1280-by-800 IPS touch-screen display. It runs on an Nvidia Tegra 2 processor with support for Adobe Flash, HD video conferencing and playback, and mobile gaming. It includes a 2.1-megapixel front-facing camera and 5-megapixel rear camera, as well as a mini-HDMI port for full 1080p video playback. It's 0.51 inches deep. Asus said the device is ideal for those who want to enjoy multimedia content on the go but still use the tablet for business-oriented tasks.

On that note, the Transformer can – ahem – be transformed into a full-fledged notebook via an optional docking station with full QWERTY keyboard. Asus said the Transformer can offer up to 16 hours of battery life "to our best estimation." It will be priced between $399 and $699 and be available in April.

The Eee Pad Slider, meanwhile, is similar to the Transformer except that it has a slide-out QWERTY keyboard instead of the docking station option and is 0.66 inches deep. Like the Transformer, though, the Slider runs on an Nvidia Tegra 2 processor, includes a 10.1-inch display, features Android Honeycomb and includes a 2.1-megapixel front-facing camera and 5-megapixel rear camera. The Slider also includes optional onboard 3G connectivity.

The Slider will be priced between $499 and $799 and be available in May.

For the Microsoft fans, the Eee Slate EP121 is a 12.1-inch, Windows-based tablet with a 1280-by-800 multi-touch display. It runs an Intel Core i5 processor and Windows 7 Home Premium. The tablet (slideshow below) includes Wireless-N, a mini-HDMI port, two USB ports, a card reader, and a 2-megapixel dual webcam. The device also includes Flash support.

The Eee Slate is available in 32GB and 64GB versions and has up to 4GB of DDR3 RAM. It will cost between $999 and $1,099 and be available at some point in January, though Asus did not specify an exact date.

Finally, the Eee Pad MeMO is a 7-inch, Android Honeycomb-based device that runs on a Qualcomm Snapdragon chip. Users can write notes on the device with a stylus tip, while the media note text app transform handwriting into text. Like the other devices, it includes 1080p playback and dual cameras.

Jonney Shih, Asus's chairman, described the MeMO as "functionality meets simplicity." The device's small form factor makes it easy to hold in one hand or slip in a shirt pocket, he said. For those who want more flexibility, there is a separate, MeMIC media phone extender, Shih said.

The MeMO will be priced between $499 and $699 and be available in June.

Shih unveiled the new products at this year's Consumer Electronics Show, which will feature the introduction of 80 tablets this week alone. Shih said options are good for the consumer and talked up the options that Asus provides to its customers - choice that its rival Apple does not, he said.

"We admire companies like Apple who offer great innovations, but they provide very limited choices for the customer," Shih said.

Different kinds of customers have different kinds of needs, he continued. "The best way to serve them is to provide choice." Asus provides the best of both worlds; innovation plus choice, Shih said.
