I have used Mobile Internet Explorer and Opera on Windows Mobile Edition touchscreen phones (XDA II), as well as Web on Symbian phones (Nokia E90 and N95) and I must admit, the Safari web browser on the iPhone is by far the best device in its class when it comes to web surfing. Of course, nothing beats a desktop or laptop for this purpose, but for a handheld pocketable device, the iPhone comes close. You can actually surf for hours without feeling tired. The easy finger-flicks, double-taps and multi-touch pinch and zoom makes this all possible, even on a 320 x 480 screen resolution. Coupled with seamless integration with wifi, 3G and EDGE connectivity, the iPhone is yet to be beaten, IMHO. Previously, the Nokia E90 with its 800-pixel widescreen was the best I have used.
