Microsoft fan boy that I am, I looked up Windows XP Pro today. It looks like Win XP Pro is the Win2K upgrade vs Win XP Home which is the WinME upgrade. I noticed on their list that XP Pro includes CD burning built in. I'm not sure if that's good or bad. I suspect I will still use some commerical burning software since I want to make different types of CDs but it does seem like it's about time that writing to a CD is part of the OS (like writing to a floppy, HD etc)
