Do you have a GBA SP or a Micro?
If so, get the DSi, but for the better hinge as opposed to the screen. I don't really notice a big difference with the screen, but I noticed a big difference with the hinge when mine broke! Granted, it lasted a long time, and I played the crap out of it -- and Nintendo gave me a brand new DS for 30 bucks.
If you don't have a GBA SP or a Micro, it's absolutely worth having the Slot-2. The GBA has an enormous library of fabulous, wonderful, excellent games. If you can find a SuperCard Lite for the Slot-2, you're good to go.
