I love the idea of Mobile Me having just really looked at it last night. I want the functionality of address book/mail/ical being mobile and updated instantly. My question is why can't my leopard server that i am running at home be updated to support this without the help of mobile me? I understand that i need some type of exchange server but I am new to using server and am learning my way around. Can someone give me a laymen's idea if or when i will be able to host my own data and update it from multiple machines?
