WikiHistory Versus the Text Book

Today in class, my group researched Buddhism.  We barely even used the text book.  We found everything we needed on Wikipedia, and the text book only backed up what we had already found.  I think Wikipedia is more useful, especially with the iPads.  Pretty much everything on the internet is compiled into presorted and pre-sifted Wikipedia pages.  Even if you can't find what you are looking for, there is a huge chance that there will be a link right from the page to what you want.  It also lists the sources, so if we wanted to research more in depth, we would already know where to look.
