So it seems that I've downloaded 100 or so free apps and am about to start buying them. Unfortunately, for every good app, there are 10 copy cat apps that try and sell the same for more. I want to stream video over 3G and wifi so I've heard that Air Video is the way to go. Then I heard that Plex is better. There are many more too. How do I know which app to purchase??? Also, does anyone have a list of apps that you use everyday? Thanks.
