Appleinsider reports that Apple will expand the use of magnets beyond its recent addition to the MacBook Pros' MagSafe power connector which is designed to safely pull away when yanked rather than drag your MacBook Pro to the floor.
According to the rumor site, the upcoming Intel-based iBook will incorporate an entirely magnet based latch technology. At present, the Mac laptops utilize a small magnet to pull a small metal latch down when laptop is closed. In the future, they claim that a stronger magnet will hold the screen shut.
The Intel iBook is also described to house a 13" display, built in iSight, Apple Remote and retain the white enclosure.
There have been a number of rumors surrounding the Intel iBook. At present, the latest expectations pinpoint the iBook replacements to come in March/April.
