What do you intend to do with the pictures you take? That would help define what processing needs you require. In addition, I would focus on learning how to shoot your camera and take meaningful pictures. Special processing could come later. You're putting the cart before the horse.
I tend to agree with you in that, at least for me, I’m really all about “learning” photography as a study. That would come first for my goals. I know many take a much more casual approach and in and of itself that’s certainly as valid as the studious route. Horses for courses
I will say however that any of the current software solutions provide for a great way to review one’s pictures and learn a whole bunch about what went right and more importantly, what went wrong. Like most photographers I learn quickest through my failures and in my case Lightroom shines a pretty bright spotlight on what went wrong both technically and compositionally. In the field I usually have a bunch of irons in the fire juggling all of the parameters I want to use for a shot. There’s usually some degree of emotion involved and I’m pretty attached in that moment. Looking at the photo later, in software, tends to be more pragmatic and many times I’ve looked at the compositional results against the technique and the data and realized, only then, why my thought process at the moment was flawed.
I feel like a good editing solution can be so much more than just manipulating pictures and to that end almost all of the currently available editors would be great for a beginner if applied to a learning curve.
