I'd want the 3DS more than the iPod xD since I game more than I listen to music and with SD cards the 3DS can double as am MP3 player and you are only limited in size by how big of an SD memory card you can afford. xD
I originally got my DS lite and Pokemon Diamond as a birthday present from my sister. I doubt I would have gotten one other wise. And I'm so happy I did get it. xD I now have a DSi XL that I got last July which I adore, and only got because my DS lite is falling apart. It still has life in it but it's old and used. xD I figured since I have over 20 games for the DS it would be a waste to stop playing it just because my system died... cuz srsly I love mah games....
I've been okay, got some bad news as far as a home loan was concerned but I'm coping with the fact that I'll never be able to move out of this hell hole... at least not any time soon. I've been playing lots of Pokemon as I got the new game on Sunday. xD
