I was reading news.com this morning and came across this quote:
Microsoft wants to get your whole house running Windows Vista.
In what is being billed as a limited time offer, Microsoft will let those who buy a boxed version of Vista Ultimate Edition purchase discounted licenses for up to two more PCs in their house. The cost for each of the additional PC licenses is $50; for that amount, consumers can install the Home Premium version of Vista on the other PCs.
I think people will like this. I am checking for the official release on this.
