Same. I love it. The things I replaced in the 8 years I've had this machine: Stock HDD -> Samsung 840 SSD, Keyboard (failed within 3yr warranty, they shipped me a new one overnight), and the trackpoint cover. Oh, and the OS, from Windows 7 Pro to XUbuntu. I would love a higher density display but that's about it.
I am thinking of finally upgrading to an X280 or an X1 but I am afraid the keyboard will be too much of a downgrade.
