According to a leak, Lenovo is apparently working on a new ThinkPad X200 that features a CULV processor. While this rumor is not confirmed, it would make sense since Lenovo has themselves admitted they are thinking about creating a CULV ThinkPad in the future, though they did not commit to a timeframe.
The ThinkPad X200 models currently feature a SL-series Core 2 Duo processor. This has made the price go up considerably, but with a 1.2GHz Celeron M chip, the cost would decrease, as would the voltage use. The new system would also have a 160GB hard drive and 2GB of memory.
Pricing is not known, nor is a release date. It may not even come to pass. We'll just have to wait and see. But it would make sense in this economy for Lenovo to be looking to drop their price point a bit.
