Interesting post by our friend Harry McCracken at Technologizer today, pointing out that HP's gone dead silent about the Slate ever since it announced plans to acquire Palm. Harry was at The Big Money's Untethered conference today, and HP CTO Phil McKinney was on stage, where he "talked about the downsides of using existing operating systems for new types of devices" and "extolled the virtues of webOS." Interesting topic, since the Slate very prominently ran Windows 7. When pressed, Phil said he couldn't talk about unreleased products, which is a big change: it's been six months since Steve Ballmer first
