Pros: Twice as good as Portal One Awesome voice acting / Very entertaining

Cons: Slow start for people already familiar with Portal One. Personally, I don't see any replay value. Others disagree.

Pros: Good quality audio Great improvement over built in sound card -- you can hear a difference with any speakers Connected to my front audio jacks Works great on Windows 7 64bit SP1 Drivers are ok

Cons: Avoid the additional software Uninstall "Creative Auto Update" -- this is a sales and marketing tool

Overall Review: I'm happy with my pruchase and I recommend this product to you
