3DS had 3 big problems at launch: high price, worries about 3D/doesn`t work all that well when moving frequently (does put people away) and lack of games.
The high price has been taken care of;
3D, unless Nintendo upgrades the technology, will probably keep people away over fears of hurting their eyes and provide a good experience;
Games of qauality are still scarce. They are coming, but they are not still here.
3DS lack of DS success has probably more to do with lack of casual software then anything else.
I think Vita will be a successful platform and mobile games won`t stop it nor DS. In the end, it`s all about the software.
Vita and 3DS will have games that people want and that they won`t find anywhere else. More, having iOS like software maybe be a good thing for Vita, but probably will be overlooked if not publicized correctly, seeing as it`s not what people "see" when they look at Vita.
I still find it hard to believe the iOS games will make handhelds or home consoles go away. Just to imagine how much an entire industry would suffer because of that... how many would survive if this market collapses? They just aren`t ready to change and adapt.
