Purpose for device:

This is outside my area for sure... what are examples of how a breakout box like this would make GarageBand more useful? What does this do more easily than other methods? Just OS integration? (Not to sneeze at that. Or maybe a massively lower price would be enough

)
And I know the rumored specs are prelimary... but wouldn't more inputs (like optical) be important? Are those big plugs common for consumers? (But maybe this is "prosumer," not consumer.)
Hmmm, lemme see if I can summarize, as I have been dealing with the exact issues that would be dealt with in this box.
(
NOTE that everything below is simplification. An unfortunate circumstance in discussing audio is how there are exceptions to virtually anything you could possibly write in short form and the technical details on most of this stuff is both long and tedious. If you wanna, you can find it online. Get ready for printing dozens of pages and many nights falling asleep reading them.)
A. Junk microphones require no external power source. The are DYNAMIC which means that they operate with the small amount of signal actually generated by the physical action of the diaphram in the microphone. Better microphones are CONDENSOR, which (for the most part) require Phantom power. Power is sent through the XLR connector (the large 3 pin connector) to energize the microphone. The benefit is a stronger signal coming out of the microphone with dramatically less "noise" or unwanted junk signal.
With a cheap dynamic mic, usually the GAIN (amplification) of the signal is adjusted to provide a usable recording level, resulting in lots of noise as you are also amplifying everything including the unwanted stuff, like line noise picked up from nearby electrical devices, like power bricks or motors. It is like amplifying a whisper in a normal room; unheard room sounds become annoyingly loud.
With a quality mic (condensor) the
original signal is louder and cleaner coming from the source (whatever you are recording) producing better results right out of the gate. A decent condensor mic is not expensive and a very nice one can be had for 150 dollars and up. Incidentally, if you want to see possibly the best microphone made in America, check out
www.telefunkenusa.com to read about a company that produces exact reproductions of the most beloved microphone, maybe, in history. The original mics are now worth about 20k each on the open market and the new versions start at 6 grand. The website is very interesting and has a lot of information on it about how the company came about and technical details about this "uber-mic." Cool to read even for non-audio people.
Note that some better headset mics, while technically condensor, don't require phantom power. The small size of their diaphram allows the manufacturer to "pre-energize" the mic at the factory and it lasts the life of the microphone.
The short of it is; better signal at the start guarantees better quality down the line, in any case.
2. USB can be problematic for audio input, although it is usable. One big problem is "latency," a delay that occurs as the signal is encoded by the "box" and sent through the USB port. It means that if you are playing an instrument or singing and listening to the signal at the computer, it isn't realtime, but slightly delayed, which can create timing problems in performance and is, at the least, a pain. Usually, because of this, you monitor the sound with headphones somewhere else up the line, like at the USB box before it encodes it and sends it through the port. That will give you a realtime signal and not the "talk-radio-echo" effect you might hear otherwise. The slower the bus, the more compression the "box" has to do, the greater the latency. USB 1 is slow. Also the bus is shared among all devices.
Also, the USB port is only marginally suited to handle audio. Most USB equipment, like hubs, expect all the information to be in small chunks. Streaming data, like audio creates, can throw it all for a loop. Griffin recommends plugging directly into the machine because if you go through a hub, IT MAY NOT WORK. Their recommendation is not made lightly. Griffin makes a hub themselves that supports USB audio signals, if you are port-short. They sell it at their web site. It is not a gimmick, it is a solution to a serious problem with using standard USB hookup logic with an audio streaming device. Firewire would work better for this, I would have to imagine.
3. Mini-plugs suck No kidding! Mini-plugs are awful. They are delicate, they are small, they tend to be mechanically cheap. They often make poor contact internally, they wear out really quickly and get noisy and one false move with a device, headphone or microphone, can pull the wire right off the plug or bend it to the point of damage. As Bart once said, they both suck and blow. They were created for lightweight portable devices and for that they are fine. Honestly, even there, there should be a new standard, in my opinion. A $600 dollar iPod with a 39 cent headphone port is laughable. The fact that it works at all is surprising to me. I would guess a lot of replacement headphones are sold. (I am not an iPod user.)
4. Most audio-only companies are slow to create and update drivers, especially for cheap devices. For example, I own a two USB audio input devices that Apple sell at their stores (they are mentioned above). Final Cut Pro won't run when the drivers for one of the boxes are present in the operating system. HUH? What is the deal with THAT? The company doesn't seem to be in a hurry to fix it, remaining one large step behind the operating system updates and application updates. For them, it is nothing but an expense. After all, you already bought the box, they got the profit and you would expect the driver update for free. Not high on their "to-do" list, I guess. The second box never worked right. I think it is poorly engineered. The company has directions from technical support on how to "whack" the USB bus using System Profiler so, maybe, you can get it working again when it just stops. Then again, you might just have to restart. ARRRRGH. So both sit, unplugged, on a shelf.
Griffin's USB interface (Powerwave), on the other hand, works with the native Apple drivers and create no conflicts (at least for me).(GRIFFIN=Good people.) At the moment it works perfectly, as advertised. Lesson: don't expect a company making $1000 audio boxes to worry too much about the software for a $99 dollar box. The response will probably be underwhelming at best.
5. According to the rumored specs, optical i/o is included. Makes sense as Apple is starting to include optical connectors on their machines.
6. Native Firewire audio drivers in the operating system won't just make this box possible but will allow third parties to create new products using those drivers. I expect a minor flood of Firewire interfaces to follow this product to market, and the more the merrier.
I'm ready to plug in tomorrow, if Apple delivers as promised.
