The form factor isn't speculated upon (it could be shaped like a big iPhone or a small MacBook) but the industry predicts that the MacBook Air will have no cables whatsoever!!!

From WiMax for networking through power induction for charging, to wireless USB for peripherals.

An Apple insider told Wired today that the company's new ultraportable, expected to be seen in public for the first time tomorrow, has an extremely thin profile and is shaped like a teardrop when closed — thicker at the top behind the screen, tapering at the bottom behind the keyboard.
"It's unbelievably thin," said the source.


The device is made of aluminum and glass, and uses the same design language as recent Apple consumer products: black on silver.
Is this cable-free design the face of things to come?

Steve Jobs is widely expected to reveal a new MacBook at Macworld on Tuesday morning, and with the rumored name being "MacBook Air."


Most people are expecting a conventional sub-notebook — a super-thin, lightweight laptop that ships without an optical CD/DVD drive. The MacBook Air may also dispense with a wired Ethernet port, according to rumor. It will be a purely wireless device, relying solely on Wi-Fi or other wireless technology for its connectivity — hence the "Air" moniker.
