This card will bring a new dimension in sound to laptop owners whom either, just like their 5.1 sound when playing games, or significantly improved audio for listening to digitial tracks. It WILL bring a new level of audio to notebooks. All for around $130.
No doubt it will be built-in to future notebook models.
I'll get the Audigy2 ZS for Notebooks, mainly because I'm pleased with Creative's hardware overall (despite their lousy drivers!). Also, EAX Advanced HD support is a vast improvement for gamers like myself.
