DescriptionAn ornamental design depicting a 2-in-1 convertible notebook design based on the IBM 9552 ThinkPad 700 series and potentially bearing a Type 3 Model M6 keyboard assembly, but with a display that can move to cover the keyboard area and resemble a tablet computer. Whilst no 700-series ThinkPad was made like this, the concept was later implemented on the IBM ThinkPads 750P, 360P and 360PE.
