Mac is more than just an e-mail service, it’s an entire package from Apple. For $99 a year, you’ll net yourself an e-mail address that ends in “@mac.com”. If this cool moniker isn’t enough to turn you over to the side of Jobs, the additional features of this service will. You can publish photos for everyone to see, have a personal webpage hosted for you without the need to worry about bandwidth, keep multiple Macs in sync with each other, have blogging capabilities, get free storage with iDisk for backing up files, and a whole lot more. Though $99 may seem a bit expensive at first glance, remember what you’ll be getting with it. This e-mail service is not recommended for Windows users since you won’t be able to take full advantage of the .Mac services offered.
