Yes, you've seen the unboxing and all other manner of granular coverage for Nintendo's new DSi handheld, but now you can see the thing in action via the magic of YouTube. Embedded below is the requisite unboxing, a helpful browser speed test and a hopeless attempt at sticking in the R4 cart for a bit of homebrew. The good news is that the Japanese DSi fires up an English DS game just fine, so those slightly-confusing region lock concerns can be put to rest -- certain DSi-specific games won't work for everybody else, but the DSi fires up regular DS games from wherever with no problem. Import away!
