Well I've spent hours looking and different apps that seem to do many different things so I'll just say what I'm looking to do and ask for any suggestions as to apps I can purchase. My wife is going to use the iPad, in part, as a sales tool. So she will need to be able to show potential customers pdf files and Powerpoints. While we are getting the 3G version of the iPad, I want to be able to load these files directly onto the iPad just so she has quick access to them. I've seen some good apps like Pages, GoodReader, and PDF Reader Pro that all look like they can do the trick for PDF, but maybe not Powerpoints. So I'm just wondering if anyone has any suggestions before I start blowing $4-8 on each of these apps trying to find the right one. Ease of use is a big plus.
