Feature:
Very easy to set up, and it's digital connections are very flexible. The only downside is the 1/8th inch connections for analog audio, but hey, for under $100, who cares?

Quality:
High quality manufacturing. Solid.

Value:
Amazing sound for the price ($80)

Sound:
An excellent upgrade to my laptop's sound outputs. I use it for my home stereo/MP3 collection laptop, and it sounds terrific.

Feature:
Has optical out, but don't use it. New Powerbooks have optical ports, so useful there...

Quality:
working fine for > 12 months

Value:
great for < $100

Sound:
Beats the soundcard in the Mac Powerbook in handling strong signals... no distortion when recording synths to GarageBand.

Support:
M-Audio email support is slooooow... I had a use/application question, not a problem...

Feature:
For free, you get 2 in 2 out simple...cheap

Quality:
Its ok, sturdy enough to be dropped from small heights, plastic case doesnt scratch easily. Although some drops using the line in were noticed. Really bad driver support.

Value:
Like i said, i got it free, and for free it does what it does.

Desirability:
just a piece i picked up free and tried to mess with

Sound:
Gives nice sound especially with hot signals. Have slight problems with low gain when using phantom powered mics

Ease of Use:
Driver support is horrible. Supposed to work with Pro Tools M-Powered v7, but lacks the correct drivers to be recognized. Also the fact that it does not conatin any firmware whatever, it has a hard time recognizing it already has drivers installed. Tries to reinstall old drivers every time it is pluuged in.

Support:
M-Audio offers almost no support for this device because they give it away in most deals, and offers only a small amount of any driver help. Digidesign doesnt offer any driver recognizing help either.

Overall:
Does ok for free
