iPhone, iPad and windows

[rdgeorge]

Do you really think that carrying 4 devices (iPad, iPhone, Macbook Air and Windows PC) is better than carrying just one paper planner?

No, but I have at least one with me and they are always synchonized. I just don't use the PC on my desk at work for GTD - I use the iPad right next to it with a wireless keyboard.

I capture stuff with paper, but would never go back to an all-paper system. Several years ago I lost a Time/Design planner which was very difficult.
