It would be killer feature since there are no commercially manufactured compact mechanical keyboards with trackpoint on it — right now you can go with Unicomp EnduraPro (but it’s still full sized), or (if you’re lucky enough) you search ebay and wait for one of the rarest IBM M13 spacesaver version (not likely). There are also some modern keyboards like Tex Yoda — but still it’s not serially produced, people are waiting it for a long time, right now there are around 4000 requests on the massdrop — and all because of trackpoint.
