Apple just dropped the mother of all WWDC keynotes, and they really kept to their agenda. Lion, iOS5 and iCloud. No hardware releases at all.
Lion
Nice new features, similar to previous major OS X upgrades: mission control, full screen apps, multitouch etc. What’s not so standard is the low low price of US$29.99, putting it on par with the previous “minor” Snow Leopard upgrade.

iOS 5
This was truly where the keynote blew my mind. An entirely new way of showing app notifications, putting it finally on par with Android. Apple also included a few new features like tabbed browsing in Safari, Reminders and iMessage that could easily kill off developers with similar functioned apps, and some decidely un-Apple ones such as using the volume button as a shutter in Camera. The biggest feature in my opinion is the cutting of the cord. No more syncing with your computer once you get an iOS device. All syncing is now done over the cloud. Even iOS upgrading will be done over the air.
Update: In the iOS 5 video there is a mention of AirPlay mirroring. Huge feature for those with Apple TVs. You can now play games and show webpages on the big screen without the need for a cable.

iCloud
Apple finally caught up with Google on cloud services, and they’re really aggressive. They finally realised no one likes to pay for cloud services, and is charging absolutely nothing for iCloud. iCloud syncs documents, photos, mail, calendars, contacts, music, books and apps across all your Apple devices, and even windows PCs.
