I believe nds is the best current gaming machine.Maybe the best ever alongside ps1-ps2.Although it first had only casual games it is interesting how many hardcore games have come up.Great ideas even with average graphics was something only possible on ds mostly because of its popularity.I play a lot of rpg's and ds has plenty of them.Plus(very important),there is no loading at all.Every game is much more friendly this way.Dual touch is not necessary,only bigger screens maybe.It's funny how much better it is compared to psp (in terms of gameplay) which is a fine machine in my opinion and which i also own.I also think that ds success was responsible for the production of the equal successful wii.
