Happy Father's Day everyone. I'm a real estate professional in Tucson, helping people to buy and sell their homes. I've been using an i-Pad for several months now, and I'm always interested to know about apps that will lend themselves well to my business practices. My immediate need is for a good "to do list" app. There are many available, but I'd appreciate knowing the ones with which you've had the best experiences. Thanks for sharing your thoughts. By the way, even though I've been a PC user since 1982, I'm seriously considering changing over to an i-MAC. Any insights you can share in that regard would also be of value. Thanks again.
