Apple Talk: The 10 biggest announcements at WWDC

This year's Apple Worldwide Developer Conference was all about software...

that Apple's competitors have long differentiated themselves from iOS by developing features that iOS lacked, such as cut-and-paste and better notifications. The rest were inspired by iOS so a little reciprocity goes a long way.

6. Location-aware reminders

Apple ads famously feature the phrase "There's an app for that" to highlight the ubiquity of third-party software that makes the iOS devices so diverse and capable of being personalised by users.

However, I honestly can't recall hearing about anything like location-aware reminders. The feature lets you set alerts and reminders based on GPS-determined location. For example, 'Call your client' as soon as you reach the office, or 'Don't forget the milk' when you walk into a supermarket.

iOS 5 iMessage

Some are already claiming that iMessage - Apple's answer to BlackBerry Messenger for iOS users - signals the death of SMSPhoto: CNET/CBS Interactive

7. iMessage

Another innovation borrowed from a competitor, in this case RIM. The BlackBerry's proprietary messenger system, BBM, lets users send messages, photos and other media to any other BlackBerry user over RIM's network. iMessage does the same for iOS devices, sending free messages and media to other iOS users.

There have been apps that replicated this functionality, most notably PingChat, but reliability was poor. Some people are already claiming that iMessage signals the death of SMS, which is premature given it only works between iOS devices.

Nevertheless, one suggestion circulating after the show was that the keynote was the first the mobile carriers knew about iMessage and its potential impact on SMS revenues from iOS users.

8. PC and Mac-free

We are living in a post-PC world, at least according to Jobs. Accordingly, why do we need a PC or Mac to which to tether our iOS devices? Apple cut the cord to the Mac and PC to rapturous applause. It's consistent with its iCloud service, with the Mac put on the same level as the iPad, iPhone and iPod touch - a device.

Gone are the days where an iOS device had to dance its initial awkward, time-consuming dance with iTunes. The cloud is the hub and the platform now.

In addition, all software updates will be delivered over the air by delta updates - in other words, updates containing only the bare minimum of data. Analysts have already estimated that cutting the cord will open up vast new markets for Apple's iOS devices.

9. iTunes Match

Jobs saved iTunes Match for his 'one more thing' piece. The feature lets you scan and match your complete iTunes music library and download it to all your devices. This feature includes tracks that have been copied from CD and music that may be of, ahem, questionable origin.

Any music not available via the iTunes store has to be uploaded to iCloud and backed up. No Spotify-style streaming yet, as many expected, but that surely is only a matter of time.

Lion OS X autosave Versions

The autosave feature of Lion OS X is probably the most understated announcement of WWDCPhoto: Apple

10. Autosave in Lion

This is probably going to have the biggest impact on the day-to-day life of most users, yet it's one of the most subtle and understated of the new features in Lion. It quite simply represents a huge improvement in working with documents.

We've all lost parts of or whole documents through failure to save. Now, as on the iPad, the document is auto-saved in the background. The whole process of hitting 'save' is over for Lion users.

Furthermore, the versioning system looks incredibly useful and practical. It may prove to be an end to the woes of lost files and versions. In a year's time, we may not even recall the pain of lost changes to documents. And good riddance, too.
