As you'll see from the range of handsets we've reviewed here, there's no single perfect device. For that matter, there's no platform we'd absolutely suggest you steer clear of. Two new options - Palm's WebOS and Android - have muddied the waters. With the HTC HD2, even Windows Mobile comes good.With the HTC Hero and the Motorola Dext we find the Google open-source platform is maturing. Nokia's Maemo OS is also an enticing proposition, but it's let down by the hardware. And WebOS, with its multitasking and ability to make sense of multiple continuous contact modes, is also compelling.The one interface that seems to have stood still could actually be Apple's, although it's hard to argue with the incredible inventory of apps that customers can draw upon.In the end, however, we had to make a choice of the best smartphone based on the best mix of phone, contact, web browsing, interface and design.The iPhone 3GS fell down on the first two, but ruled elsewhere, while the dinky Palm Pre won us over in almost every way. But that's just our opinion. Smartphones are as personal as it gets in the world of technology, and so is the decision about which you prefer.
