Super Slim 1.8" HD from Samsung

Samsung announced today a new 60 GB 1.8" hard drive. While that storage capacity is nothing new (the high end iPod uses a 80 GB 1.8" disk), the form factor of the disk is: Samsung's new product uses perpendicular recording technology to fit 60 GB on fewer platters, which allows the disk to be only 5mm thick (a thickness only obtained with 30 GB disks until now).
Apple could therefore use this disk to release a future 60 GB iPod that would remain 11mm thick (against 14mm for the current 80 GB).
On top of its very thin form factor, that disk also has the benefit of running very silently.
