Purists I think are not fans of mini-tune, it takes away an important skill one should learn. As for which guitar, that's a loaded question. What one person likes someone else may not. I'd find and play which ever is most comfortable for you. I started on electric and then can to the conclusion that the music I most enjoyed was acoustic based. Not only that, but for me playing acoustic without the option of distorting the sounds, provides no room for sloppy playing. And when I do venture back to electric it will be a little easier, as for me it's a little tougher to play acoustic compared to electric.

In saying all that, it's what choice works for me, not the same path everyone takes. Choose what your comfortable with, cause if you love the guitar you will be more inclined to pick it up.
