Love is in the Air at Macworld?

"There's something in the air," say the banners around San Francisco's Moscone Center, home to Macworld 2008. Given the secretive nature of Apple announcements, that's more than enough to start the rumours flying.

So in addition to our speculative new product list yesterday, let us add the MacBook Air. Apparently, allegedly, a friend of a friend at a third-party Apple vendor has let slip that this ultra-slim, ultra-portable lappy will be the star of the show.

Adjectives such as "thin" are matched with adverbs like "unbelievably" when it comes to describing this potential new addition to the Mac line-up. The slimline design is helped by large helpings of solid-state memory – up to 96GB – to dispense with clunky old hard drives.

The Air is expected to sport a 13in screen and borrow the aluminium and glass look of its MacBook brethren. The display owes more to the iPhone, however: conflicting rumours include a touchscreen, or a wider touchpad with added multi-touch.

Expect a few other tricks, like built-in WiMax or HSDPA, to go with that 'Air' tag as well. If all goes well, it could be blowing into stores this week.

But for now it's just a rumour, so keep your eyes peeled here for full coverage from 5pm UK time.
