aligning v-brake pads is just as easy/difficult as the ones in your link; simple single bolt per pad; I see no benefit in changing over to a caliper style.

in fact there a a few reason not to; your current frame has mounting posts for v-brakes, the caliper brake you looked at does not mount using them, having the unused posts hanging around is going to be ugly
bigger issue, the caliper uses a different cable pull than your current v-brakes, in order to convert it you will need new brake levers as well.
