There is finally a machine with the screen option I want available, but only as a pre-configured one. It includes the smart card reader. I have a T520 - also bought pre-configured - and the palm rest cracked after around 1 year, because of the amount of flex where the smart-card reader is. Might this also be an issue with the X1 Extreme? Are the palm-rests constructed from aluminium, rather than plastic on the X1 Extreme? The T520 has a plastic palm-rest with a roll cage substructure that clearly wasn't good enough. Alternatively, is it possible to buy the plastic insert of machines that do not have the smart card reader?
