The T440 is no longer being manufactured (the current model is T480). I have a refurb T460 at home[aside] which works great out of the box with any Linux distro and has a keyboard that is a pleasure to use when contrasted with most laptops out there. And the repairability also means that you can buy a cheaper model and only once you need it extend the sdd/ram when you need it. [aside]: it has a top IO panel that every now an then decides to stop working, including the power button mouse and keyboard, although usb ports continue to work. The only option at that point is to hard reset (I carry a paper clip in my keychain :-/). Haven't found an explanation for the problem. If anyone here has any ideas, please reply. I've googled all around. I have found no correlation with anything so far.
