Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Next MacBook to Include Glass Trackpad, Due in September?
According to Weintraub's sources, the new MacBooks will be thinner than the current MacBook and MacBook Pro designs while slightly more rounded. The case is said to be made of one piece of aluminum and bears some similarities to the MacBook Air. The trackpad on the new notebook is to be made of glass and support multi-touch and the use of gestures, but the notebook will not incorporate a multi-touch screen.
Finally, Weintraub expects the new MacBook to be released at the end of September.
Based on the description, it appears these new MacBooks will be an evolution on existing laptop designs and not a radical departure into tablet designs. Of course, no one expected Apple to abandon the traditional notebook design, but the use of the term "MacBook Touch" may have confused some. Of course, these rumors don't preclude the possibility of some sort of tablet based device as well.
