If the reports are true about the new MacBooks, you may want to consider buying a sleeve to not only protect your investment against scratches and light bumps, but also to protect your legs from the MacBooks heat. These laptops run very very hot. Wrappers MacBook sleeve and lap protector, tailored for the 13inch MacBook, insulates against temperatures up to 250 degrees centigrade which should be just enough to guard against unaturally red legs. Made with 76% rubber and 24% cotton. They are available with a trim in six different colours: black, purple, red, blue, green and orange. £17.99 from Wrappers.
