The T series still looks like the old IBM Thinkpad design. Not sure about the X series, the other Lenovo laptops are all of a different design. They look more ike an HP or a Dell with a cheap curvy plastic shell. I've always liked the IBM Thinkpad design as they feel better made than the other models out there, ie: metal hinges, harder plastic, rubberized coating, etc. I'd probably go with a T60.
