Purely from a data entry perspective, my inclination would be to simply use the matrix writer for inputting the data. It's easy to activate (left-shift MTRW), and once you've established the first two entries and started the next row, it "knows" that you are entering a 2-column matrix. Subsequent entries could be entered in sequence with the enter key and possibly RS-COPY and RS-PASTE for the repeated entries if desired. A final ENTER places the resulting matrix on the stack.

You could then use either the matrix commands or convert the result to a list with AXL and process the result as a list of lists. If using the list approach, a final AXL will convert the data back to matrix form.

While I'm sure you could find a solution with fewer keystrokes needed for the computational part (the sheer number of commands available on the 49/50 dictates deep/lengthy menus), I'm looking at this more from a practicality standpoint than a keypress competition. When entering data, I think there's great value in seeing more of the data while doing the entries. Navigating within the matrix for copy/paste/correction is also intuitive. The matrix writer handles this nicely.
