With the new activation and things that they are doing it is getting tough to just "Get it off friends". I am testing this and everytime it leaks the serial that leaks gets blacklisted ASAP. So if this does happen the serila wont activate and you will only have an OS for 14 days. They are keeping kinda close eye on this OS. This is M$ baby. They cant have what happened with XP happen again.
I am not saying that people wont. I am not saying that there wont be ways around it. I am just saying whith what they are talking about for specs (Right now) and what they are talking aobut for security that it just might not be worth it to upgrade right away.
Eventually everyone will use Vista. Even me. But i wont right after it gets released. To many patches and bugs will be discovered right away. I wil stick with the security of XP for about a year till they work out the kinks of Vista.
