黑莓 PlayBook

????你很可能曾经听说过黑莓手机生产商RIM公司的PlayBook。但由于其销量甚微，人们可能早已将之抛到了脑后。但该产品也有一些优势：搭载所谓的QNX操作系统，提供多任务窗口，用户在多个应用程序之间进行切换时甚至比在iPad搭载的iOS 5下还要顺畅。但其致命弱点在于，不提供独立的电子邮件客户端软件。这真的是RIM出品的设备吗？去年，该公司这款设备仅发售了20万台。现在，零售商们为清空库存，可能得降价甩卖。

????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.
