I tend to agree with @fellfrosch's points. Just as most-if-not-all keyboard accessories meant to be used with a tablet, "converting" it to a laptop don't work for the very same reasons; the end result is not a good tablet nor a good laptop

It is essential to have a solid connection between the lower part containing the KBD and the upper part with display, and to get the balancing right the battery just has to be located in the lower part, else the construction is very uncomfortably balanced.
