ASUS is getting ready to lay the smack down against Apple’s MacBook Air with its super slim U36. The U36 promises better performance than Apple’s system with either an Intel Core i3 or i5 CPU. The Air has a Core 2 Duo processor.

They also promise up to 10 hours of battery life on a 4-cell battery, compared to the Air’s 5-7 hours of battery life. It will also use NVIDIA’s Optimus graphics with the company’s Super Hybrid Engine. The device weighs 3.2 pounds, just slightly more than the slim Air, and has a thickness at 0.75-inch with a magnesium alloy shell. It looks rather blah design-wise though.

If you want to find out about a new device, just check out the FCC. They all pass through those hallowed halls eventually. This time we have some details on the LG XNote LGX30.

This ultrathin laptop features a 11.6-inch 1366 x 768 resolution display and we wouldn’t be surprised to see it at CES 2010. Some other features of the LG XNote LGX30 include: Windows 7, a 3-cell battery, Weighs 1.74 pounds, Bluetooth, Webcam, Solid state drive (SSD), Wi-Fi, GMA500 graphics.

Here’s yet another Windows 7 machine debuting today, this one from LG. The X-Note T380 is a 13.3-inch ultraportable powered by a Core 2 Duo SU3700 with 4GB of DDR2 RAM, a GMA 4500MHD graphics set, 500GB of hard drive space, 802.11a/g/n WiFi and Windows 7 Home Premium.

LG has also updated its X-Note P510 to include Microsoft’s newest OS, but is otherwise exactly the same. Nothing yet on price or release yet, but we should know soon.
