The big perk that comes along with purchasing a Nintendo DSi instead of a regular Nintendo DS is the Internet capability. With Nintendo's new DSi model you can go online and surf the web as well play other users over an Internet connection just like you would on an XBox or Nintendo Wii. Setting up and connecting the Internet on your DSi is quite easy to do and you will want to set this up right away to take advantage of all of the fun features.
Use the Internet settings on your DSi to find a WiFi point
Use the DSi Shop to download the DSiBrowser using your 1000 points
Go on the DSiBrowser and start surfing!
