Lenovo is known for making some robust notebooks that perform well but have zero sex appeal. The machines have looked basically the same since IBM owned the ThinkPad brand. Today Lenovo announced that it has added Windows 7 to a couple new machines called the SL410 and the SL510. The notebooks hit overseas already, but today is the official U.S. coming out.

The two notebooks are similar with processor options ranging from dual-core Celeron parts to Core 2 Duo processors. The SL410 has a 14-inch LCD while the SL510 sports a 15.6-inch unit. Both screens are LED backlit. Graphics for the pair are from Intel X4500 integrated GPUs. System memory is up to 8GB and storage is up to 500GB.

Both machines use a 6-cell battery and have optical drives built-in. Other features include available WiMax, Bluetooth, spill resistant keyboards, multitouch track pads, VoIP ready microphone, and more. The notebooks start at $529.
