And it's here

UPDATE: you can see the full Steve Jobs keynote here.

The rumors were close and Steve Jobs finally presented the news on the Apple world (while the keynote movie is not available at Apple's site, you can read it at Engadget):

• There's in fact a new notebook, MacBook Air, the thinnest notebook ever (watch guided tour here)
  
• 1,6 or 1,8 GHz Core 2 Duo CPU, 2 GB memory, 13,3'' LED-backlit screen
  
• Multi-touch trackpad that allows performing iPhone-like operations
• No optical drive, but a nice wireless feature (Remote Disc) that allows connecting to nearby computers' optical drives
  

And a lot of other new products were announced:

• Movie rentals service on iTunes
• New price for Apple TV and software updates
• A wireless Time Machine-enabled hard drive: Time Capsule

Apple has done it again :-)
