“It will be mid-2008 at the earliest before we could have a production-quality release,” said Utzschneider. Much of that time will be spent adapting XP to run and boot from an SD card. He also says that engineers will have to develop a new BIOS to allow the computer to boot from flash.
Utzschneider stresses that pricing of the scaled-down XP hasn’t been finalized yet and even adds, “You should not assume that Windows on the XP is a done deal.” However despite the ominous tone of that last sentence, he says that Microsoft is committed to developing a quality port of Windows XP, but that “we still have a lot of work to do to complete the effort.”
