Exactly. Some people just learn differently. I've only been playing for about, oh, 5 years (has it been that long already?). At first, I tried books. I had a bunch of different books about learning guitar. I spent more time reading and researching different threads of thought than I actually did playing. Then I spent a decent amount of money on a highly-recommended set of video lessons (13 DVDs!) that I just never really took to.
I seem to do best with a guitar instructor. I think being able to stop and ask questions about the theory of what we're playing, or alternate chord voicing, etc at any time and being able to explore something in depth on a whim -- while playing music -- really jives with how I, as an individual, learn. The only books I retained are of the reference type (theory, chord voicing and scales). I still have the video lessons, but am saving those for a few more years for my niece, who is showing interest in learning guitar, in the hopes that she might do better with them than I did.
These damn kids these days may learn better through an interactive, video game environment. Some might not, and prefer video lessons, or that fancy book learnin'.
