In the world of iPads, the Air is heavier than the Pro

In 2008, at the Macworld conference in San Francisco, Steve Jobs pulled the original MacBook Air out of a manila envelope, thus ushering the era of ultra-light, "Air" Apple devices.

And although some MacBook Air variants did put on weight in the following years – there's now a larger, 15-inch variant – the company's Air lineup more or less stayed very light and nimble.

But in the company's most recent iPad lineup, introduced at yesterday's "Let Loose" event, the "Air" moniker makes little sense.
