It is being rumoured that the next generation of MacBook will be thinner than the current MacBook and MacBook Pro designs and will also include a glass trackpad and support multi-touch and the use of gestures.

The MacBook is also said to be made of one single piece of aluminium and will bear some resemblance to the MacBook Air.

Finally Seth Weintraub of ComputerWorld writes that he expects the new MacBook to be released in September.
