iOS4 vs. WP7 in Browser Speed Test
This week developers started receiving Microsoft’s test units, which will allow them to test the performance of their apps for WP7 instead of using an emulator. The test smartphones are produced by Samsung and LG and have a Technical Preview version of Windows Phone 7, and guys at NewsGeek decided to compare its browser speed with iPhone 3GS' that runs on iOS 4.
Since the difference in speed is so huge it is noted that both of the phones used 3G network (not Wi-Fi) and iPhone 3GS is a completely finished product, while Samsung's test unit is a prototype with an unfinished OS that is still in development.
Newsgeek also found Internet Explorer in the Windows Phone 7 to be "surprisingly competent and quick" though it was mostly built off of IE7's desktop version.
