Samsung's touch-based user interface always impresses me, and the Tocco Lite keeps up the good work. Getting round the handset is intuitive so there's no need to resort to the manual, and vertical menus are large so that accuracy with the finger isn't a problem.
When it comes to entering text, there are several options. There is an accelerometer in the handset and when you are in the messaging software, you can twist the phone in your hand to get a full QWERTY keyboard in landscape mode. This is very responsive to use two-thumbed and you can toggle a T9 word recognition system on and off depending on your preference.
In portrait mode, you don't have the QWERTY option. Instead, there is a numberpad, again with T9 toggle, and some handwriting recognition options which work well with a fingernail as long as you go quite slowly.
Samsung implements its good old widgets system on the Tocco Lite. There are three main screens, which you pan between with a finger. They can all be populated with widgets that you drag onto screen from a sidebar. The sidebar slides out when you tap its tab.
There are some connected widgets such as one for the weather (AccuWeather); links to Facebook and MySpace, which take you to their websites rather than being mobile clients; and a YouTube link. Trying YouTube over GPRS was not a pleasant experience. Jerky, blocky, unwatchable.
Other widgets include links to photos, the calendar, music playback controls and favourite contacts. I love the widgets system but feel Samsung has a way to go before it is perfect. One major problem is that widget icons are often large so you can only have two or three on screen at once. The multiple home screen system helps with this issue, but I am sure Samsung could make some of the widgets smaller.
