English to Chinese Tech/Engineering IT (Information Technology) smartphone OS

Android 4 made a good start to improving the interface, but it's still inconsistent. It has even introduced some new metaphors and inconsistently implemented them, so it has a ways to go to be a polished OS. Windows Phone 7 is proficient but can do little beyond social networking, and it's unclear whether Microsoft will try to make it a full-on platform like iOS or Android. Then there's BlackBerry OS, which is being replaced later this year with a new OS -- assuming RIM can finish the job, given its many delays and declining revenues.
安卓4在改进界面方面开了个好头，但仍做到不够。它甚至引入了一些新的界面元素，但实施起来缺乏一致性，所以它远远谈不上是一款尽善尽美的操作系统。Windows Phone 7很出色，但除了社交网站方面外，基本上没有多大作为；我们也不清楚微软会不会竭力将它打造成像iOS或安卓这样功能完备的平台。 另外就是黑莓操作系统，今年晚些时候它会换成新的操作系统——假设RIM能完成这项任务，考虑到它多次推迟、收入减少。
***I suspect through all this***, the iPhone 4S and the forthcoming "iPhone 5" will remain the best smartphone.
