Only Wii.

I don't like handhelds, so no reason to get a DS.

I didn’t own any of the 2 myself, but my family had a Wii, my sister used it more than anyone, and she also had a DS, the reason why we had a wii was to play party/family games together, during that time, I had a PS3, PSP and Xbox 360, never used the Wii to play anything for myself.

I had a DS. Bought 2 actually. I was trying to buy a Wii for a spell, but this was during the period when they were almost impossible to find. I tried 6? 7? 8? times and gave up. I suppose that's really the main reason I never had a Wii. After my PS3 library grew a bit, I no longer cared if I got one, so that was a factor too.

F**k Ubisoft!

Ouch! lol

I had both of them. I had more fun with the Wii than the DS

I have both. Great systems.

Own both.

Had a DS first and then bought a Wii later.

Definitely played Wii more, even if I played on the DS a lot too.

I own both but spent a lot more time playing on the Wii. Hell, I spent a lot more time playing MKwii than DS
I bought the DS beacause I wanted to play Spirit Tracks, Phantom Hourglas and Metroid Prime Hunters. Ended up playing some other games too.

I owned both or at least my family did.

DS was the point at which I started realising I don't care for handheld gaming. Pokemon was the only thing I really invested any time in.

Wii brought me many loved experiences including Wii sports/resort, twilight princess, Mario Galaxy, Metroid Prime 3/Brawl/Mario Kart.

Keep in mind I was 10 to 12 years old. My parents were the ones who bought me things, how could I ask for another console when I already had a home console and a portable? I actually think by that time I was asking for a mobile phone
