The word entry would be easier as well, instead of hitting a key three or four times you would scroll quickly to a letter and press one key -- or even type a few letters and SCROLL through common words that have that combination of first letters.

In fact, ergonomically, I would argue two repetitive motions (scrolling and clicking) is faster than moving your finger or thumb about a number pad and hitting a key some random number of times, move the finger to the next letter etc...
