I.. I just downloaded the iworks suite (pages, numbers, keynote) along with atomic web. I just downloaded a few .ppt and .doc's for class. How do I open them and edit them?? Do I need to download something else, maybe a file manager? Any help would be great, thanks!!! Ps- I was considering to buy a pen for the iPad to take notes.. Does anybody have any experience with that, and if so what app worked the best..?
