"Make your laptop feel like 'one of the guys/girls'. Make it feel perfectly at home with your other household tools. Now a hammer, saw and a laptop can form a meaningful, friendly bond to last a lifetime.".

So, the next time some one asks what's the coolest gadget you got, show them the world's most expensive carpenter's level - your MacBook!
