Macworld Expo 2008, the biggest Apple event of the year, has officially started! The event started with a keynote speech from Steve Jobs. Macworld Expo 2008 is currently ongoing so we'll be giving you updates on the event as soon as we get them!

To start things off though, one of the first things announced in Jobs' keynote was the Time Capsule, a companion product to the Leopard's Time Machine. If you remember, the Time Machine allows Macs to back up its data every hour so that there's virtually no risk of accidentally losing data.

With the Time Capsule you can backup every Mac in your house wirelessly into one Time Capsule. Physically speaking, a time capsule comes in the form of a hard drive (an AirPort Extreme variant, also with an 802.11n spec).

The Time Capsule will be available in February and will come in two versions. One will have 500 GB that will be available for US$ 299, and the other is a whopping 1 TB version and has a pricetag of US$ 499.

We'll be back with more Macworld Expo updates for you. Check back for updates!
