Very nice. Every year I am getting more and more tempted to make the switch from Windows to OS X. I like my iPhone but have always preferred Windows to OS X however I am not very excited with the way Microsoft are taking things with Windows 8. Also I love the hardware and design. They only company who comes close to Apple's design is Asus in my opinion and even then they are still not quite there. Does anyone know if the SSD is a standard SATA drive or a custom built in one (i.e. not user upgradable)?
