Three things which I would die for:
1) Keychain syncing (So annoying registering for a site on my iMac, then needing to remember a ridiculously long password on my MacBook Air, then perhaps a week later needing once again to remember it for my iPhone...)
2) "Save to iCloud" option on iWork, just hit Cmd+S and press the iCloud icon and bam, it saves. Also opening documents from iCloud would be great
3) Multiuser iCloud iDisk - would be great for sharing files from...
Jason from TechAU has created a video face-off between Microsofts voice recognition software, called TellMe, and Siri on the iPhone 4S.
Jason tries to create a meeting, send a text message, check the time, and play an artist. While Siri gets each command correct, TellMe fails miserably every time.
