Yeah, definitely install it so you can see how bad it sucks.
I made my first "song" which was only an imported wave file so I could try the included effects, clicked "save" and it took about 10 minutes to save to the cloud.
It kept telling me about the free "Expand II" so I went to the store (right there on the menu bar

) and bought it for $0.00. The download started and after about one hour it still wasn't finished so I gave up and canceled everything. During that one hour my quad core was at 100% on all 4 cores. I have never seen that happen with any software before!
I was actually going to purchase Pro Tools because "everybody uses it". I'm not going to purchase it anymore.
You don't know how good you have it with Sonar until you try someone else's software.
To be fair to Pro Tools, I assume that there is probably an issue with my computer/audio interface that is preventing it from working properly. I probably could contact Pro Tools support and get it straightened out, but I'm not going to.
