What motivated my choice? the brand awareness, value for money and the size of the machine ... oh and also the fact that this map was created spécialmenet for Apple. I use it to record guitars, bass, sax, percussion, and the dijeridoo make hip-hop/electro prod.
My config: MacBook Pro unibody 15 "(4GB RAM) KRK Rokit 6, Berhinger preamp (no top), guitar fender telecaster custom 70, line 6 amp valvotronix ...

UTILIZATION

drivers? I'm Mac! Mac RAM! no drivers, just a software "Maestro" that works to hell.
The software I use is Logic Audio, and it goes very well with Maestro.
On the Duet can not save a lot of tracks simultaneously (2) but I preferred to take an interface that focused on quality rather than quantity but it is only my opinion.
The latency is almost zero, see zero (FireWire 800 requires) great lover!

GETTING STARTED

Installation? Apart from installing the software "Maestro", the rest is plug and play! And frankly it easy as always Mac! neededTo not man, frankly it's easy ...

OVERALL OPINION

I'm using it for only two months, I have used no other but I heard from some friends of other interfaces and I find that there are no pictures! quality Apogee is the appointment ...
The price / quality ratio is excellent, plus it has a sturdy brushed aluminum shell as my Macbook ... of the ball!
What I like most: all the big button controller (very handy), the cables that allow flexibility in the recordings are very practical and well thought out, the Maestro software controller that allows all your gear direct your computer and especially the sound quality! pfffff terrible. besides all this coupled with my KRK, it kills!
What I like least: going to say sth, I would say two more things coming into top would be too much but hey, for what I did (recording instrument 1 to 1) the fact that serious.
I would do the same choice without hesitation
