A question from Yahoo! Answers:
Please explain for those who told me Windows Vista is no good and why I should keep my XP Pro. Thanks!?
First, why spend money to replace what works? Is there a particular functionality that you need and can’t get on XP?
Second, Vista has higher system requirements than XP, so a computer that is running fine with XP may magically become sluggish once you upgrade to Vista (as a matter of fact, this is exactly what happened to some people who upgraded from Windows 2000 to XP).
Third, there may be compatibility issues between Vista and your hardware (again, look back to XP’s early adoption; there were a variety of problems, including a few cases of XP destroying BIOS chips).
