Though I am not a Vista fan it does have a few features that you may find
useful.
Here is one if you do publishing

Also, with each reboot, a restore point is created
so any files that have been deleted or changed can be restored by simply
right-clicking on the folder
they were in and opting to restore previous version.
Additionally Vista has built-in non-destructive repartitioning
and a memory check diagnostic.
Due to Vista using considerably more resources than XP...
none of the above reasons are sufficient for me to use it...
but Vista does have at least a few possibly useful features.
Additionally, Vista has added security as compared to previous versions of
Windows...
though of course, some people consider it extreme nagging <G>
