"pretty decent processor" - that could be anything. Was it a celeron? Athlon? Pentium? Barton? We have no idea what it was. For all we know, it could be a Celeron 2.0ghz, god forbid, which performs even worse than a 5-year old AMD Thunderbird that run on 100Mhz FSBs.
Scrolling sucked? This is a video driver issue. If you don't have the right driver, it will not interact with DirectX9 (or 8.1, if they didn't upgrade), and thus you have your sluggish scrolling--well sluggish anything.
I don't believe that Windows controlled your behavior. What a blatant blanket statement for your trouble. It is your BIAS, your lack of knowledge and experience that controlled you. Please, enough of the stereotypes and bigotry. It really makes me sick.
*I am really suprised you burned through "finder". I don't know anyone who uses the default Windows software to burn--when Nero or Roxio SHOULD have come with the burner, and are FAR superior alternatives.*
That decision alone serves as a metaphor for your knowledge--and it taints what little factual information you have posted as your "experience".
