There's no shortage of smartphones on the market, but with so much choice just which device should you plump for? The answer depends on what you most need your smartphone for.
Do you need a device that excels at email or one that's optimised for browsing the web? And will the best smartphone for emailing or browsing also keep you entertained on a long flight?
A smartphone's power comes as much from its operating system as it does from the capabilities the vendor builds in. To help you at least narrow down your choices, we tested four smartphones, each based on a different operating system, to find out which platform is better for particular tasks. To represent their different platforms, we tested Apple's iPhone 3G, based on a mobile version of OSX; the HTC Touch Dual, based on Microsoft's Windows Mobile 6.1; Nokia 's E71, based on the S60 variant of the Symbian platform; and Research In Motion's (RIM) BlackBerry Curve 8310, based on, of course, BlackBerry's proprietary operating system.
We compared how well these phones performed four common road-warrior tasks: browsing the web, sending and receiving email, taking a photo and e-mailing it, and playing music and streaming video. We felt these tasks were typical of what most smart phone users need to do, and would also test the power and usability of both the devices and their operating systems.
