I love my DSi. At first, I didn’t think that its cost would justify an upgrade from the DSlite. Little did I know how much Nintendo had in store for me with this little bundle of joy. Some of the main differences between the DSi and the DSlite is that there are now 2 built in cameras, it can access the web with wifi, it can play music (in m4a format), and new DS games will come out with extra features for the DSi. I'd say my money is well spent.
