Since kicking off our coverage of the Sony Ericsson Xperia X10, you’ve seen our unboxing video, Part 1 of our software overview, and the hardware overview. Well now it’s time for Part 2 of the software overview. In this video we compare the speed of the Xperia X10 against the Samsung Galaxy S. The X10 is preloaded with Android 1.6 while the Galaxy S comes with 2.1. These two devices face off in a stock browser comparison, YouTube load time test, and finally a simple assessment of app opening times. You will surely notice that we have opted to load custom launchers on these two devices over the stock manufacturer skin. On the Galaxy S we use Launcher Pro, which unfortunately requires Android 2.1, leaving us to use ADW launcher on the Xperia X10. By giving a demonstration of each of the two launchers, you can formulate your own opinion on which you prefer. So, press play!
