Its day-one game lineup was anywhere from craptastic to nonexistent. And, at the time, the best use of the 3D tech was the OK Go video.
As of now, aside from Kid Icarus, most of its games of noteworthiness have been ports, such as the 3 you mentioned, Tales of the Abyss, etc.
IMHO, there really isn't enough 3DS content to warrant an upgrade if you already have a working DS.
