Nintendo's DS has proven a popular follow-up to the legendary GameBoy handheld, making portable gaming increasingly immersive with its two screens and stylus control. It's so easy to pick up and play a DS that everyone from hardcore gamers to grannies, parents, teenagers and small children will find a DS game they can instantly fall in love with.

Although it sounds obvious, we want our handhelds to fit in a pocket, and not all of them do. While Nintendo has added a lot of hardware features to the DSi, it's also managed to reduce the overall size of device itself. Admittedly the DS Lite isn't exactly bulky, but the DSi is even more compact and lighter (and a little bit sexier).

The DSi, however, is designed to provide more than just gaming. It's got a built-in web browser so you can look around the net between games*, and the memory storage space and memory card slot means you can listen to music or watch videos.
