A further note:
If you plan on playing DS games regularly, you may want to keep your DS.
After playing on Pokemon Black for a little while earlier today, I can say that the colours seem washed out and the image isn't as sharp. Personally, I don't think it's worth it when I can just play it on my DSi anyway...
If you aren't planning on getting a DS, then it'll be just fine, and if you're only going to play the odd DS game from time to time, then you won't notice the difference. But if you're looking to clear your DS back catalogue (Fire Emblem, Okami...), then keeping your current DS would be in your best interest.
