Just got it last night and I love it.
It was extrememly easy to install.
Got it on sale at Best Buy for $120.
I did have to buy a USB 2.0 pci card for $30, but I still feel like I really came away with an incredible deal.
The Nero software that was included, while not extraordinarily powerful or extremely intuitive, was nonetheless not too difficult to learn, and very well endowed with features and flexibility for a bundled product. I was able to make a DVD in no time. I imported about a half-hours worth of video, and it took about 6 minutes to burn the final DVD. Wow. I was expecting much slower!! Thankfully, I was pleasantly surprised!
The only problem I ran into was when I tried to burn directly to DVD instead of choosing the recommended method (it's the bottom checkbox on the DVD burn settings dialog box, but I don't have it in front of me, so I can't remember exactly what it said -- sorry). Anyway, once I went with the recommended method of burning, it actually seemed to go faster, and I had none of the little flash frames that I got when doing it "my way" the first time through.
