The Nintendo DSi.

Although 2009 is the fifth holiday season for the Nintendo DS, the demand hasn’t slowed one bit for the popular handheld system. Here are the best Nintendo DS gifts you should consider purchasing this holiday season.

Hardware
The Nintendo DSi was launched earlier in 2009. While it includes several new features like cameras, music player and DSiWare support, the new model doesn’t play Game Boy Advance games like the older models.

Accessories
Headphone
You will need a headphone is you plan to bring the Nintendo DS with you outside. Fortunately, all models have a standard audio jack, so any headphone will do the trick.

SD/SDHC Card (Nintendo DSi only)
Just like the Nintendo Wii, the Nintendo DSi supports SD and SDHC cards for expanded storage. The 256 MB internal storage isn’t a whole lot, especially if you plan on downloading games on the new Nintendo DS model and also using it as a music player.

Nintendo Points Card
In order to buy DSiWare, you need Nintendo Points. You can buy these points in card form in 2000 points ($20) increments.

Games
Grand Theft Auto: Chinatown Wars
The popular series returns to its classic 2D roots with the ambitious Grand Theft Auto: Chinatown Wars. You can expect the same great free-roaming experience from the console iterations in this ambitious Nintendo DS title.

Mario & Luigi: Bowser's Inside Story
Easily the best handheld RPG released in 2009, Mario & Luigi: Bowser's Inside Story adds several new elements (like the ability to play as Bowser) to the already enthralling gameplay.

Professor Layton and the Diabolical Box
The sequel to one of the best games on the system, Professor Layton and the Diabolical Box features even more creative puzzles in addition to another engrossing plot that will keep you glued to the Nintendo DS screen.
