A shield is great for some things... particuarly "plugging in" lots of connections to something external. However, to add an LCD panel to my Arduino, I only need to tap the serial line and 5v and 0v if I spend $8 for a complete kit of parts (except the panel itself) for the great little LCD panel controller from ModernDevice.com (no "S" in that). It is an implementation of Peter Anderson's #117."Except the panel..." The kit lets you interface a wide range of panels to the Arduino. Hence the need to purchase it "separately". ModernDevice offer a selection. Some only $12, if memory serves.It should even be possible to drive the thing from something other than the serial out pin, but that would entail a little more software work. Why reinvent an already available wheel? There are so many other worthy projects waiting out there!!(My only association with ModernDevice: Happy customer.)

I thin the other reason is that it is a lot of fun
