Feature:
For me, the built in effects plug-ins have virtually put my hardware processors out to pasture. In the past I used to run a few plug-ins and add effects track by track with my hardware processors, but now I'm using the software plug-ins almost all the time. You really can't compete with simultaneous processing on every channel via hardware with a smaller budget like mine.

Quality:
I remember back in the day of Logic 3.5 thru 4.7. When the program crashed, you were presented with a save dialog box, which didn't always work. But it saved hours of work on occasion. Logic in it's fully OSX-ish glory runs as solid as I could imagine. Looking back on OS9. It's time to move on. The sheer stability of OSX has completely erased the hours of hair pulling (and re-booting) that I've done in the past. Using Logic on tour used to be a big problem for me. My Wife's iBook G3 333MHz with it's little 5400rpm HD could never run my files unless I stripped OS9 down to it's bare bones and offered the gods of data a goat or two. With Logic Pro 6, my new PowerBook can handle everything I throw at it and more. That sure beats dragging aournd the Beast (UMAX S900 w/ G3 300MHz, 200MB RAM, 3 Hard Drives and the old reliable AudioWerk8 Card).

Value:
$2500 worth of goodies in a $1000 package. You can't beat that. Unless of course you think that all software should be free.

Desirability:
It's been getting better every year. Except for that um, year or two it wouldn't run in OSX. The fully automated features are great.

Sound:
I've been using logic for years and the software synths that are bundled with the current version are much easier to use than many stand alone products I have tried to use in the past. I haven't had any trouble with creating arrangements of wholly software based music on my Dual 1GHz G4 with 768MB Ram. I haven't really noticed a defined sound that Logic has. I've worked with everything from Industrial to Acoustic and I've always been able to flesh out the overall sound however I wanted.

Support:
I'll rate this 10 out of 10. I used emagic's tech support once in 1998. I haven't had a problem since then. I had emailed their tech support and got a response withing 24 hours and which included a detailed solution to my problem and some other tips to related problems I have yet to experience.

Overall:
I'll be satisfied with Logic for as long as emagic keeps making it. I've shopped around for other products in the past, but I keep coming back to Logic. It works equally well for the intermediate level as it does for the pro level and the $1000 package has enough goodies in it to keep you knob twiddling needs under control. Speaking of plug-ins such as the ES2. Many software synths try to emulate hardware to the point of utter frustration for your mouse. Emagic's plug-ins are designed from the ground up to be easy to use in a virtual environment and doesn't have button b next to knob a just because it was easier to use physically.
