I am saving a nice little spot on my home page for a tool that will help me to transfer documents from my iMac/or PC to my iPhone. I especially would like to be able to save Excel Lists and PowerPoint files on my iPhone. Has anyone tried out the apps now available (I think i saw three). I have already bought over $100 in apps - hey don't yell at me - so I want to be careful to get the right one for Documents. Please help me guys!
