Then I think that you would be hoping for someone else, as per topic title, who has bought the Nexdock XL!
The one observation that I would make is that I am using the lapdock display as the primary and sole display i.e. phone display turned off / not joined or mirrored.
(I actually also have a mini-mouse for use with the lapdock so I am not overly dependent on either touchscreen or touchpad - so I may not have noticed some gremlins - but both do work for me.)
