Pros: Inexpensive- With rebates, I only paid $69 + tax at CompUSA.
Cons: Unusable, poor mfr. support, software isn't the most stable either.

Well, not just mine but many others too. You see it turns out anyone that has a notebook that uses the ENE cardbuss controller will have some issues, and that's a lot of people!
Before you buy it - check your device manager to see what's on your PC. The problems vary somewhat but crackling and popping to some degree is pretty common. You may be able get rid of it by trying various workarounds including operating it in "standard mode" but you'll lose some features and audio performance. A lot of smart people have spent a lot of time trying to get this card to work on their PCs with the ENE controllers and there's still no definite/universal fix. At this time there's 19 pages on the subject on the Creative forum. Creative for their part isn't supporting the problem by coming up with a fix, they've had lots of time now. Bottom line - if you have the ENE controller and still decide to purchase be prepared to return it and waste some valuable time like me.
