Remember the tiny Intel notebook leaked last week? Previously known as the NetBook, Intel's (not so) secret weapon on the UMPC market finally got specifications and some more high-resolution photos. Extremely similar to the Classmate PC sub-notebook, the new ultra-portable device from Intel is expected to pitch at the educational market as well.

The first rumors about the so-called NetBook emerged from an US-based OEM worker that leaked its initial specifications. It is now confirmed that the Eco PC will come in a 10-inch form-factor with a 9-inch LCD display. Intel's notebook weighs a little more above one kilogram and will aim at the sub-$400 market.

As we have previously reported, the Eco PC, formerly known as NetBook is powered by an Ultra-Low Voltage Intel Celeron chip running at 900 MHz. At the moment, it is unknown whether Intel will release an Atom-based version of the computer, as part of its NetTop initiative. Also, as far as the non-official technical specifications have been detailed, the system will come with 512MB of DDR2 RAM, maximum 40GB hard drive, built-in 802.11 b/g WiFi and Ethernet.

However, one of the leaked pictures claim that there will be three versions of the sub-notebook, that will only differ in storage capacity and in the amount of memory aboard. The three units will be named ECO PC 2G, ECO PC 20G and ECO PC 40G. While the ECO PC 2G will be the lowest-end offering (packing just 2GB of SSD and 512 MB of RAM), the ECO PC 20G and the ECO PC 40G will both come with 1 GB of DDR2 memory and 20, respectively 40 GB of conventional hard-disk drive space.

The 9-inch LCD display will be powered by Intel's 915GMS integrated graphics. The notebook is reported to run at native resolutions of 800 x 480; however, there is no word on whether it will be capable to reach higher resolutions or not.

The new sub-notebook from Intel seems to be quite a competitor on the UMPC battlefield. Soon, HP will release its HP 2133 UMPC, while Asustek is making the final adjustments before sending its Eee PC 2.0 into the battle.
