Microsoft Courier cancelled

Gizmodo reports that Microsoft has canceled Courier, the book-like device that was expected to go toe-to-toe with the iPad and Android tablets. I can't help but wonder if HP was its hardware partner. Now the owner of Palm, HP isn't likely to maintain any interest in making mobile devices that aren't built around WebOS—even if it still makes the Windows 7-based Slate, which is a more traditional full-bore tablet PC.
