Macs are good travel laptops. My windows and linux installs never reliably go to sleep on their respective laptops when I close them -- and I cannot be bothered to figure out whether it's a hardware problem, or a software problem... I'll just bring the mac which does sleep reliably. It also has pretty good battery life compared to my other machines.
