"Android phones whisk users across the web more than 50 percent faster than the iPhone, according to a study that compared the two top mobile OSes performance when downloading web pages.
The study, conducted by mobile website optimization company Blaze.io, involved more than 40,000 downloads of web pages belonging to the Fortune 1000 companies. Android loaded pages 52 percent faster when rendering full web pages than the iPhone. On average, Android phones took 2.1 seconds to render non-mobile optimized web pages, while the iPhone took 3.2 seconds.
Android bested the iPhone on site loading time a whopping 84% of the time."
Dolphin (hardware acceleration for Honeycomb (Android 3.0+))
Opera Mini (claims to be fastest)
Skyfire (supports Flash, 2,000,000 downloads)
and many more. Here is an article on an Android browser shootout.
My second phone, the Samsung Galaxy S, runs Android 2.2 and is very stable. The ability to view Flash is an important factor for me for both of these devices, which is why I gave my iPhone to my sister. The one item I do miss is the iTunes Synchronization however I am debating getting out of the iTunes/Appstore altogether and find a replacement. Any recommendations for OS X music management software would be appreciated (please leave a comment).
The long and short of this is that while my perception is that Android is indeed faster at loading web pages, the key thing that wins my approval is multiple choices. YAMMV! *
