Something to point out is that Creatine can indirectly affect neurological adaptations, just by virtue of improving your performance and endurance during training. It depends of course but on average that's an added advantage and can result in a bigger % improvement from creatine.
Also as Chris mentioned beginners will usually have a much larger potential for strength increase from neurological adaptations, but that only goes up to a point, so for example you might be able to increase by even say 5-10lbs each week because there is a lot of room for neurological and energy adaptations, but eventually you reach a plateau of your actual near-max muscle capacity and get to much slower increases at which point you are mostly making improvements through actual muscle growth and muscle cell adaptations. Even for beginners that point can be reached in relatively few months with the proper training.
Finally, while the word 'supplementation' often seem to makes people want to say 'unnecessary' as an automatic response, just think of it in terms of nutrition. From our previous conversations for example, Chris appears to consume a very large amount of meat. That's not the case for everybody, especially for people on a diet or more conventional diets (which might include also dairy, eggs, etc, all of which don't contain it).
While it could be argued that meat can provide protein at acceptable prices (me and Chris already had this discussion in another thread), the same -can't- be said for creatine, just because Creatine supplements are sooooooo much cheaper compared to the amount you get in meat.
So, if you eat tons of meat all the times like Chris, maybe you'll still do ok without creatine supplementation, but in general I think it's a good idea to add at least some amount of creatine for the same reason you might want to include a multivitamin to your diet, it's super-cheap, no real side effect for a little extra and can only help out, and most people's diets tend to not be perfect especially compared to the increased need under intense training.
