Nokia N900

We begin by looking at the most powerful smartphone in Nokia's catalogue. Their newest smartphone is the first of its kind; it's the first mobile phone ever to use the open-source Maemo OS (previously seen in Nokia's selection of tablet computers). Say hello to the Nokia N900. The Maemo OS gives the Nokia N900 a finger friendly interface, and in addition to that, the mobile has a built in QWERTY thumbboard, and it has more methods of interacting with the phone than ever before. It's not solely about the UI, though, because the Nokia N900 is packed to the gills with high-end features. A 5 megapixel camera makes for superb photos, the media player is stunning, and with HSDPA and GPS, the Nokia N900 certainly isn't short of connectivity options.

Palm Pre

However, in the world of interfaces, there's one phone canes both of the phones on this article, hands down: the groundbreaking Palm Pre. You see, the Palm Pre is built on a completely custom operating system named WebOS, which is easily the slickest, most user-friendly interface which has ever been released. With intuitive gesture controls and finger sweeps for EVERY action on the phone, the Palm Pre also brings in tight integration between its different apps. Book a ticket for the movies using one app, and the Palm Pre automatically updates your calendar with the time. Multitask loads of different apps, and watch the Palm Pre run without slowing down at all. When it comes to interfaces, basically, the Palm Pre is unbeatable!

HTC HD2

So, there's the Nokia N900 with its Maemo interface, and then you've got the Palm Pre, which uses WebOS. And then you have the HTC HD2; it holds the record for the biggest display ever, on any mobile phone. Coming in at a whopping 4.3 inches, it is truly vast, and the WVGA, 800x480 resolution makes it genuinely easy to interact with things like scrollbars and drop-down menus. However, the HTC HD2 actually does a superb job of making it so you do not have to go into the standard Windows menus that much, since sitting atop the operating system, the operating system is HTC's patented Sense UI, where you do everything through a range of finger swipes and sweeping motions. It is incredibly simple to use, and it (along with the truly awesome 1GHz Snapdragon processor) is what makes the HTC HD2 such an unmitigated joy to use. Of course, it's not all about being raw processing power, a phone needs to have compelling features and the HTC HD2 has them in spades, from the 5 megapixel camera, through GPS, to incredibly fast HSDPA internet access (not to mention the superb Opera Mobile web browser), which is why many people see it as the best mobile phone EVER.
