Android 2.2的Javascript执行速度完胜Apple iOS 4

Android自从系统升级到2.2以来加入了一个高性能的JIT，并对其Dalvik JRE进行了深度优化。其结果是Android 2.2的Javascript执行速度大幅度超过Apple的iOS4.

在性能各方面都受限的手机上，Javascript执行速度的快慢直接影响到browser的反应速度和用户体验。Apple要加把劲了

Andriod web browser speed is already satisfying, would hardly "notice" if it's go faster.

Issues I have with Android is.

1. Man the settings are ALOT and HARD! brand new Android phone out of the factory there are hundreds of settings! hard to imagine once I starting install tons new apps to it.

2. I don't like 3rd custom UI - namingly HTC Sense. Man it's freaking slow! and pointless!
Sadly I can't even find a way to turn this HTC Sense off on my HTC Desire. (I went to Manage applications -> Force stop the HTC Sense and didn't work!

3. 界面的滚动和browser/photo pinch-zoom 有明显的延迟，停顿。 which has very neg impact on user experience.

4. OS 的感觉像一款改良的Symbian. similar in the way how it's install apps and manage them. lack of the feeling as "Native".

抱怨贵抱怨, 总的来说还是不错的.

我觉得 IOS, Android, WP7 得比较完全符合 OSX, Linux, Windows.
真实老鼠的儿子回打洞阿.

顺便问以下, Andriod现在可以装什么导航系统?

there are a few, go to Android marketplace check out.

but Google is releasing out a free navigation app soon. I've already download it called "Navigation". but seems now available to our region yet.

现在Andriod要和iphone拼了，开始往javascript上想招了。试问问，现在拿iphone上网的能有几个？大网站不都有自己的app了吗？要比性能，比硬件，iphone不一定行，可也要比比软的。

to be honest, Android has no chance beat iPhone. to me Android is a "geek" phone. while iPhone is a "dummy" phone - my daughter started use iPhone fluently since 1.5 year old.

however Android might be quite successfully in terms of market shares - 对山寨厂商来说 (HTC, Lenovo...etc)这是唯一的救命稻草.

iphone打电话不行，上网不行，性能不行，硬件不行，这位敢情是专门黑iphone的。。。

froyo的js快速和dalvik没关，而是引入了V8 jit引擎. dalvik只管java

do not use it even it is top one.

Andriod手机没俩仨月就落伍, 这个也受不了呀.

Android 还有很大的潜力，不光是手机，还有平板，今年是平板年，等3季度Nivida的Tegra2平台出来，性能秒杀ipad.个人认为Android最终会成为移动设备的主流。

True. Dalvik optimisation might have helped in making the browser itself run faster though.

Intel也开始加入到手机CPU的竞争了，接下来一两年智能手机/tablet市场会有大的进步

If I setup properly as in pulling all the shortcuts to the desktop then yes, but point it it's freaking hard to set it up!

This phone is not for dummies! not that I don't like geeky toys!

and iPhone is dummy proof out of the box

Steel就是Android自带的浏览器的fork，经常也被用来称呼Android的默认浏览器。Android browser也是用Java写的，你要还是不信的话，自己去http://android.git.kernel.org/上面看源代码吧。
