Hi,
The only disadvantage from switching from Win98/98SE to XP would be that if you have any older programs that will not run with XP.
Some image/photo programs, such as Microsoft Picture It 99 (very, very good image program) is not compatabile with XP. Or 2000 for that matter.
Here is a link to show how to check the compatibility of your programs with XP:

This link explains how to check your computer for compatibility with XP; also has step by step instructions on how to install XP.
Best wishes,
