Just today (after my confirmation) I recieved $250 and a DSi. Right now I am slowly making this thread via the DSi's keyboard on it's web browser (powered by Opera [available for 0 points]). The use of the web browser is fun but it takes time to get used to (including no flash or java [possible upside because there are less ads]). A major downside is the 700 something by 800 something resolution (so get used to scrolling where you want to see).
I'm not sure if there any DSi-only games, but if there are any, can anyone list some good ones (available from a store in Canada)?
Also, with my DSi, I got 1000 download points. With the points I suggest getting Wario Ware and a paper plane game (the name escapes me).
So on the final note, I suggest only using the DSi's web browser if you are extremely patient, but the rest of the system is absolutely wonderful (I like the wii-like menu the most)!
