Speaking of Vista...

In our home, we have three computers networked together. All have Windows XP. Unfortunately, one of our computers is so archaic, it doesn't even have a pentium processor!

Last night my husband was trying to print a document and it wouldn't let him because it doesn't have enough memory!

Suffice it to say, we need a new computer. So, that leaves me with this question.

If I buy a computer that has Vista on it (seems like there is no choice in the matter), do I have to upgrade the OS on my other computers as well? I really don't want to do that.
