I recently got a ThinkPad X100e.It had a dual-core version.The Singapore online site said that the processor was an AMD Athlon Neo X2 Single Core.If I'm not wrong,the single core version is the Athlon Neo.Really hate the regional differences.
And getting just the dual-core motherboard(the processor is soldered onto the motherboard.Damn it)to upgrade the processor is going to be impossible...
