I have a 5205-S503 and it really whips the llama's ass.. no wait.. that's winamp.
It is pretty sweet tho. I have two complaints about notebook.
1. XP Home instead of XP Pro is a complaint, but easily fixed...

2. Can't use LCD screen and video out at same time. (at least I haven't figured it out yet.)
So, unless either of those seriously bother you, great choice in a notebook.
