BlackBerry PlayBook
Ok, chances are you've actually heard of Research in Motion's PlayBook. Given its paltry sales, you may have forgotten about it, though. As plusses go, it uses the so-called QNX operating system with a multitasking pane that lets users juggle apps better than even the iPad's iOS 5. The lack of a standalone email client, however, is its Achilles Heel. This is a RIM device? The company shipped just 200,000 units last quarter. Now, retailers may have to slash prices to move inventory.
