Hi, this is my first post on this forum. I am waiting on my first Mac a 14" iBook that will arrive early next week. I have been a Windows user for years and now have to learn the world of Mac. I am very excited but have lots of questions. Here is my first one, is there a PDA that is useable with Mac? I have a color Toshiba windows unit that I need to stick on Ebay now, but to replace it with what? Thanks in advance for the great responses that I know will be on the way.
