Well, the up to three thing seems to apply to "small business editions" at least they did with Gateway. Only problem was, it would only work on a Gateway computer. I learned this the hard way, as we had 2 computers, bought the third as a Fujitsu laptop, went to install Office only to get the message "This is not a Gateway computer."
I now refuse to purchase this type of s/w from the computer mfgs.
