Apple’s last major reveal in addition to the operating systems is the iCloud service. iCloud, as you’d expect, puts all the user data on the cloud enabling users to keep their data in sync with all of their devices, including iPad, iPod touch, iPad, Mac or a PC. For instance, any changes you do on the device is synced back on the cloud and updated on other authorized devices.
Some of the services iCloud will offer are Contacts, Calendar and Mail, keeping them in sync across all Apple devices and also allowing users to share the calendar with friends and family.
The Apps and books purchased from the iBooks store will also be synced, automatic backup of content over Wi-Fi, Photo Stream (up to 1000 images for 30 days) and finally the iTunes Match service. It’s a paid service wherein it matches your ripped music with the vast iTunes library and upgrades them with a 256kbps AAC DRM-free copy. iTunes Match will be released this fall for $24.99/year.
