I have been debating using .Mac service for my contacts, calender, etc. As it stands, i am also considering using it for backing up my Hard drive. Currently, i use MS entourage for my mail, contacts, calender and like the fact that it is one program with everything, but i don't have the ability to access it online if i am away from my computer. And i am using the silverkeeper software with my Lacie FW drive for backups. The one thing i don't like about dot mac is the fact that they charge you $99 / year. Just wondering what people's experience is and would they recommend it? Also, if anyone has any good recommendations on backup software to use with my Firewire Drive.
