It's not Courier, but HP's rumored slate PC is here, now. Steve Ballmer and his hardware specialist Ryan Adsdorian just showed it off, and man is it cute.
"They're more powerful than a phone and almost as powerful as a PC. Perfect for reading, surfing the web and taking entertainment on the go," said Ballmer at his CES 2010 opening keynote.
Ballmer says that it will be available this year. HP says they'll provide information on the slate after the keynote, but wouldn't say anything in the meantime. We're calling it a "slate"—well, Microsoft is calling it a slate, to differentiate from the pen-and-screen dealy that Bill Gates intro'd in 2001—but that's not its name.
It's a Windows 7 touch device, so it's nice in an accessible, netbooky (yeah, I'm guessing relatively cheap) context. But it's not exactly the Courier we have lusted after from Microsoft in our dreams (and waking hours).
Here you can see it in its various modes, movie mode, ebook mode and PC mode:
