I am thinking of buying an Apple work station, but have a couple of compatability questions. 1) Can I video-chat to someone who has a regular PC with Microspoft XP? 2) Do I still use the unique e-mail software provided by my ISP? 3) Can I load my Creative MP3 player software? Hope someone can help with one or all of these....I'm really excited about rying an Apple after so many years of thinking about it.
