Well i had my DS before my Wii, and i love it.
The controls are easy to grasp after you've played it a few times, i tend to use one hand for the stylas, and one on the buttons. But games like new super mario bros are mainly button useage, with a few touch screen moments,
I amn't sure of using it with the wii, i dont think its ready for that yet (i could be wrong) maybe pokemon? anyway, they are going to make demos available to your ds, via the wii soon. a whole new channel.. in japan in november some time.
Go for the DS lite though, the screens brighter, clearer, and also (i feel) nicer to hold. Plus they have just released a very handsome silver one!
