Is the 15-inch MacBook Air big enough to replace a desktop?

For writing, browsing, spreadsheets and video it works as a main machine, especially with an external monitor. Heavy sustained work like long video renders is better on a Pro model with a fan.

How does it compare with the 13-inch MacBook Air?

It has the same chip and design language but a larger 15.3-inch screen and a six-speaker system instead of four. It weighs more, so the 13-inch is the better pick for constant travel.

No. The Air is fanless, so it runs silent but throttles under long sustained loads. Short bursts of heavy work are fine.

What ports does it have?

Two Thunderbolt ports, a MagSafe charging port and a headphone jack. Plan on a hub or dock if you use a monitor, card reader and external drive together.

Can I upgrade the memory or storage later?

No. Memory and storage are soldered, so choose the configuration you need when you buy. Buyers often regret the base storage once photos and apps pile up.

What comes in the box?

The laptop and a MagSafe charging cable; the power adapter is a separate choice on some configurations. Check the box contents for the exact model you pick.
