i'm prolly going to get a new powerbook and i don't know much about .mac...do any of you loyal mac users use .mac?...what exactly is it's purpose, what does it do? i saw that a part of it is virus protection but is it also an application to 'surf the web'? i guess my question is do you need it?...would i be better off using a different provider or service like earthlink, aol, etc...and getting antivirus software as well...or should i just use .mac? help me out guys...what's the story? thanks for any input.
