'We as a company will need to cover all form factors,' he told an audience of students and press. 'You'll see slates with Windows on them – you'll see them this Christmas.' Mind you, if he's talking about the rumoured HP Windows 7 slate, he may not be so pleased when it appears. A recent YouTube video showed a supposed prototype which has been described as a 'trainwreck in the making.'"
