It's watching you.

While the jury is still out on just how significant an update the DSi is over the DS Lite, the American public has voted emphatically with their wallets by snapping up almost half a million of the machines since launch.

To put this figure into perspective, the DS Lite sold 226,000 units in the same time frame.

Strong DSi sales will only help continue Nintendo’s dominance of the US hardware market; throughout March the Wii and DS achieved an astonishing 1.16 million-plus in hardware sales, although it should be noted that that total is 17% down on this time last year, when the two machines shifted 1.42 million sales.
