Apple co-founder Steve Wozniak lashed out at smartphones, the MacBook Air and the Apple TV in a speech at Australia's Broadband an Beyond conference in Sydney.

Wozniak admitted to being "disappointed" at iPhone's lack of 3G support. He rejected Apple's argument that lack of inclusion of 3G support in iPhone could be attributed to battery life: "I get as much life on my 3G phones as I get on my non-3G phones," he said.

Apple's co-founder proceeded to rail against developers for championing technology over people, but managed to praise Apple's iPhone for its web capability, observing that no other smartphone yet comes close to that experience.

But Wozniak was more scathing on the MacBook Air, saying: 'I don't think it's going to be a hit," warning that the lack of an optical drive or ethernet port and the miniscule 80GB hard drive would stymie sales.

Wozniak seems unhappy about film rentals, too, warning that for many users a 24-hour rental period is too limited for the kind of lives we lead today.
