By the way: we also make software for teaching people to do things. Dozuki makes it easy to create vibrant how-to manuals.

Dozuki is great for:

• Standardized work instructions: improve quality by documenting how to get things done, one step at a time.
• Building product support sites: make your customers love you by teaching them how to do amazing things.
• Training and e-learning software: we've used Dozuki to teach over ten million people to repair electronics.
• Online community platform: build a knowledge base of expert knowledge with Answers, the Q&A engine that drives the popular iFixit Answers.

We would tell you that this Broadcom BCM 943224 module looks just like the Mid 2011 MacBook Air's wireless board, but you would accuse us of being repetitive.

Instead, let's focus on what's different. Apple rotated the "Assembled in China" sticker 90˚ and flipped the internal code sticker a whopping 180˚!

In case you thought we were joking, taking the EMI shield off reveals the same chips as last year:

• Broadcom BCM4322 Intensi-fi® Single-Chip 802.11n Wi-Fi Transceiver
• Broadcom BCM20702 Single-Chip Bluetooth 4.0 Processor with Bluetooth Low Energy (BLE) support
• Murata antenna switch module

Next up are the speakers.

The new Air boasts stereo speakers for all your Apple party needs. Just in case you want to party like it's 2011 or 2010...

You may be asking, "What's that black stick being used to remove the speaker?" That is a Spudger. It's ESD safe and heat/solder resistant. It's a must for working with sensitive electronics.

A few more Torx screws hold the lonely fan in place.

We were hoping to find a new asymmetrical fan, and we were not disappointed!

The wider gaps in the fan blades are around 3.6 mm, while the narrower ones are approximately 2.8 mm.

If you're not familiar with all the hype, the "asymmetrical" design of the fan blades is supposed to disperse sound across a wide range of frequencies, rather than just one, making fan noise "hardly perceivable."

Next out is the left side I/O board, featuring the slimmed down MagSafe 2 port.

Sitting side-by-side with MagSafe 2 and USB 3.0, the standard 3.5 mm headphone jack looks quite plain and outdated. How long must we wait until Apple announces "The New Jack"?

With dictation coming in OSX Mountain Lion, you're going to want to make sure you've got a brand spankin' new microphone.

"MacBook, send a message to my iPhone so that I can talk to Siri."

Boom! There goes the logic board.

Bam! There goes the heat sink.

Even with a new processor lineup, the thermal management system looks pretty much the same as last year. It truly is a testament to modern processor efficiency to see such a small heat sink on a dual-core processor that can crank out up to 2.8 GHz.

Here's what we found on side A of the logic board:

• Intel Core i5-3427U 1.8 GHz dual-core processor (Turbo Boost up to 2.80 GHz) with Intel HD Graphics 4000
• Intel E201B953 SLJ8B Platform Controller Hub
• Intel DSL3510L Thunderbolt controller
• Texas Instruments TPS2561 dual channel power switch
• Linear Technology LT3957 inverting converter
