Lenovo is expanding its LePad range of products for the Chinese market with three new tablets: the 7-inch S2007, 10-inch S2010, and an oddly sized 5-inch tablet known as the LePad S2005. Powered by a 1.5GHz Qualcomm dual-core chip, the two larger devices will offer a 1,280 x 800 IPS display and include 1GB of RAM. Both tablets will ship with Android 3.2 but an update to Ice Cream Sandwich will be offered later.

The 7- and 10-inch tablets mainly differ in battery life and, of course, form factor. Lenovo says the S2007 can last up to eight hours on Wi-Fi, while the S2010 houses a larger battery that can stay charged for up to 11 hours. Otherwise they both offer dual cameras (1.3MP front, 8MP back), support China Unicom's WCDMA and China Telecom's EVDO networks for 3G data usage, as well as micro USB, micro SD, and micro HDMI ports.

The Lenovo LePad S2007 is 9.7mm thick and weighs about 0.8 pounds, while the larger Lenovo LePad S2010 is only slightly thicker at 9.9mm and weighs about 1.5 pounds.

As for Lenovo's LePad S2005, the device has an 800 x 480 LTPS IPS display with a 178 degree viewing angle and runs Google Android 2.3.5. It is powered by a 1.2GHz Qualcomm Snapdragon dual-core processor paired with 1GB of RAM. There's also a 1.3MP front-facing camera and a 5MP rear-facing camera, support for Unicom's HSDPA data network, as well as micro USB, micro HDMI, and micro SD card ports.

Despite being so close in size to a smartphone, the S2005 is marketed strictly as a tablet and will make calls only through third-party VoIP services like Skype – much like Dell's discontinued Streak 5.

All three devices will be available in China next month. Although no plans for a global rollout have been announced at this point, PCWorld reports that the LePad series of devices will be sold under the IdeaPad brand name outside of China. If a recent leak is accurate, the company might have a separate tablet planned for the international market, packing a Tegra 3 chip along 2GB of RAM and a fingerprint scanner on the back.
