Now will it work with vista 64 or be xp 64 compatible as vista 64 wont have a lot of drivers or software support, vista 32 will get most.
Again like xp home and xp pro vista 64 will have safety features that would not be included in vista 32, so vista 64 better for search Internet than vista 32.
If you look at what vista 32 can do then what vista 64 can do i bet ya a lot of 32 bit vista users gonna be screaming holy murder, as their are some very juicy safety features in vista 64 that will make vista 32 users green with envy.
