that should help,

honestly chris,  im not sure how important the eraser is. i use a tablet for
digital painting (a mouse feels strange after tablet) i rarely ever flip
over the pen to erase something. i like to do erasing with the tip of the
pen because it is smaller than the end of the pen . or by selecting and
using the delete key not the actual eraser. some programs the eraser acts
just like the tip for example quartz composer. other programs use the eraser
as it should and let you do things like smudge etc with it.  still i never
use it. when you flip the pen over, the buttons are not next to your fingers
so selecting an eraser type or adding a brush to the eraser can't be done
without flipping the pen over clicking the right or middle button selecting
your erase option then flipping the pen back over just to erase is a waste
of time.  so if you are going to add an eraser option maybe make it a fast
clear all, or do something unique to your app that the other two buttons can
not do. maybe pull up a color picker or something. just a thought. rember
not everyone has the intuos 3 some may have cte or bamboo etc... which have
different buttons on the tablet itself or none at all. i would not choose to
negate the extra buttons they just won't be available for some users.

i made a little drawing app for the mouse, tablet, a multi touch DI, and
iPhone/iPod. it dosent do much but draw on the screen and leave some cool
color trails. just a novelty not really anything anyone would want to use
for anything but maybe interactive art. it makes music as well. i would be
interested in seeing your drawing program. i like digital painting.
