What he said.
I was looking out for a Zacate laptop/netbook for Christmas, but they only started appearing in the last couple of weeks so I just bought one. They sold 3 million CPUs apparently, but that doesn't mean they have been in our shops. When was Zacate announced, last November??
As long as you get something with a discrete graphics I'm sure you'll be fine, I wouldn't want to rely on the Intel graphics drivers to get me througn a graphics intense course.
