黑莓 PlayBook

????你很可能曾經(jīng)聽說過黑莓手機生產(chǎn)商RIM公司的PlayBook。但由于其銷量甚微，人們可能早已將之拋到了腦后。但該產(chǎn)品也有一些優(yōu)勢：搭載所謂的QNX操作系統(tǒng)，提供多任務(wù)窗口，用戶在多個應(yīng)用程序之間進行切換時甚至比在iPad搭載的iOS 5下還要順暢。但其致命弱點在于，不提供獨立的電子郵件客戶端軟件。這真的是RIM出品的設(shè)備嗎？去年，該公司這款設(shè)備僅發(fā)售了20萬臺?，F(xiàn)在，零售商們?yōu)榍蹇諑齑?，可能得降價甩賣。

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.
