I own a 2008 MacBook Unibody, 2.0 GHz Intel Core 2 Duo, 2 GB RAM, GeForce 9400M. I was thinking of trying out a PC and this recently announced Thinkpad X120e running a Zacate E-350 caught my eye. Would the increased graphics capabilities of the Thinkpad make up for the lost CPU speed? Would this be a noticeable step down in terms of computing power?
