All things modern.
The Lenovo X220 is a very nice looking convertible tablet but its various protrusions make it very difficult to use on a flat surface. If the tablet had some Kind of stand perhaps, it would make it much easier to use on a desk (Think classroom or lecture hall). So as usual, l have made an attempt to design such an add on stand.
This is a folding stand held in place by hinges on either side of the laptop. This is not realistically going to work as there are ports which would be covered but would have been good if it was designed in. All that would be needed were two small holes into which the stand could be clipped when needed.
Below is a detail of the hinge to show how it would work.
Perhaps on the X240?
