If you love to personalize your gadgets, here's a good alternative to the multitude of vinyl skins that you can put on your Macbook. The Karvt skins boasts 100% wood with a professional grade 3M adhesive backing that should stick well on your Macbook. It comes in different flavors of wood (pine, cherry, maple,..) as well as an artists series which looks really great with the aluminum body of the mac. A nice apple-outline detail also serves as a fool-proof way to center the panel in the back which in my opinion will save a lot of people installation headaches.
They are still on pre-orders but orders taken for April will ship on May 1st. That's $35 for the original and $50 for the artists series with 10% off on pre-orders so hit the source to check it out.
