   Two additional thoughts:
   
   - For the Table (or ChunkedArray) repr, it will actually show the first and last 5 elements of _every_ chunk. That feels unnecessary to me, and the first 5 of the first chunk and last 5 of the last chunk seems sufficient?
   - For heavily nested data, copying 5 rows from device to host _could_ actually be expensive because that can potentially be a lot of data. For the repr (`to_string()` / `PrettyPrint`) this is tackled by having an additional `container_window` to determine how many elements to print within a nested array. But I can imagine that honoring that also for deciding which data to copy will get complicated (an initial implemention just copying a slice of the actual array sounds good enough to me).
