Back then, the U1 had a tablet running a Linux-based Skylight OS developed by Lenovo, while the base laptop it attached to had undefined specs. Now, the U1's specs are clear: Windows 7 Home Premium and a 1.2 GHz Intel CULV Core i5-540UM CPU, 2GB of DDR3 RAM, and a 320GB hard drive, along with one USB port and HDMI.
The tablet is now called LePad, and is a 10.1-inch Android device running a custom LeOS variant. The screen has a 1,280x800-pixel resolution and the tablet still runs off a Qualcomm Snapdragon 1.3 GHz processor. The LePad has 1GB of RAM on its own and either 16 or 32GB of flash memory, Bluetooth, Wi-Fi, EVDO/WCDMA 3G, a SIM slot, and a 2MP Webcam.
Lenovo promises a seamless transition between Android and Windows 7 operation with Unique Hybrid Switch Technology, will allow a continuous Web-browsing experience.
For now, the LePad and U1 Hybrid will only be available in China, starting in Q1. The LePad on its own will start at around $520, and the U1 Hybrid laptop will start at a pricier $1,300, although that also includes the LePad. We're very curious to see what a year has done to make the U1 a device more palatable as an actual product. More will be posted once we've seen it more detail at CES 2011.
