Lenovo has finally rolled out the two dual core processor options for the Lenovo ThinkPad X100e thin and light 11.6 inch notebook. While the image above suggests that you can upgrade the processor for no additional cost, I think that’s just an error on the Lenovo web site. Because when you add the Athlon Neo X2 Dual Core L335 CPU, the price jumps up by $45. The AMD Turion Neo X2 Dual core L625 processor will add $70 to your base price.

In other words, the cheapest price for a Lenovo ThinkPad X100e with a dual core CPU is $494.

The base model comes with 1GB of RAM, a 160GB hard drive, ATI Radeon HD 3200 graphics, and Windows 7 Home Premium. But you can upgrade to Windows 7 Pro, up to 4GB of RAM, and up to 320GB of hard drive space. Bluetooth and 3G options are also available.
