For me, I have a Macbook and an iPhone and basically access to an iPad, though it's really my wife's iPad. My Macbook is #1 - I use it for everything I do in the world of IT consulting. My iPhone is a great companion - I use it constantly for email and occasionally for writing professional articles. I briefly used the iPad but I didn't see the need for it once I had an iPhone in my hand.
As for my wife - the photographer - she simply can't bring herself to rate one above the other. Ok, she doesn't use her older model Macbook Pro any more but can't bring herself to part with it just yet. But her iMac, iPhone, and iPad are constant productivity tools for her and each one is used extensively every day.
What about you? What's your favorite Apple productivity tool in terms of hardware? Is the new iMac your most used tool? Are you finding the iPad or new iPad2 to be more useful than you had even hoped it would be? Are the keys of your Macbook or Macbook Pro nearly worn out from constant use? Can you not imagine life without your iPhone and how do you use it for business productivity? Send in your thoughts....
