Samsung and Apple both have plans to release tablets with screen as large as 12 or 13 inches, putting further pressure on ultrabooks powered by Intel X86 processors.
Digitimes claims that the Apple unit will be made by Quanta with the likelihood that it will have a 12.9 inch screen, come out in October next year and will target the educational market.

The same wire reports that Apple will introduce a large iPhone in May next year using a 20 nanometre microprocessor, with TSMC the foundry that has the win.
