Disappointing Idol Results

I confess, I didn't watch all of this season's American Idol episodes. But I did watch the final two shows, and was simply shocked at the results.

While David Cook certainly is a fantastic singer and performer, David Archuleta has far more vocal range and control. Archuleta's performance Tuesday night was, as Simon put it, a 'knock out'.

I am curious, though... Both artists can play instruments -- Cook is great on guitar, and Archuleta is wonderful on piano. Why is it, then, that Cook was constantly seen with guitar in-hand, while Archuleta was deprived of his piano?
