Jerry is a long time Mac user and he's going back to school for Aerospace engineering. Now he has to get a Windows machine. What's the best for him? Linux? Leo says he'll most likely need Windows. He should get recommendations from his teachers, but most of the stuff he'll need is on Windows. It's pretty solid and rather "Mac-ish." The biggest differences are relatively insignificant.
The sky is the limit for options and manufacturers. Leo recommends the Dell Precision machines -- they're perfect for high end applications. Those are desktops. For laptops, Leo likes the HP Spectre and the Lenovo Thinkpad X1 Carbon. Asus and Acer have great laptops as well.
