MS to Launch Paid Security Subscription Service
Infused with .Mac? Have you ever used .Mac? This is a completely different kettle of fish.
.Mac is an Internet services package that once upon-a-time included Antivirus, but now it doesn't. However, it does offer remote backup (1GB), one-click homepages from iPhoto/iWeb, one-click Podcasting (GarageBand) as well as acting as a IMAP mail server and sync server so that bookmarks, system preferences, application preferences, calendars, contacts and bookmarks remain sync'd across multiple Macs.
In short, It isn't anything like OneCare.
www.mac.com is the place to go and get educated.
