I loved PogoPlank but I must say Orbit has already become my favorite. I have added categories in PogoPlank to a total of 9. I still had a hard time categorizing the apps....where do they belong? Now when I try to find a program....I have to check a few places before I find it. I know I'd eventually remember. Also it means or feels like more presses to get to what I need.
But with Orbit, since I already have idea where programs are on which page (habit) and the resolution is so good on the iphone, I can see the tiny icon and go right to the right page. It's great! It's quick. There is no delay at all! I really believe this is the way the launcher page should be!
