In the tech industry, we refer to the marketing ploys of a company as kool aid. You drink the kool aid and you believe everything the company says. Apple has incredibly strong kool aid, and Adobe's kool aid works well too. This is especially true when you're selling technology that's cool, because when something amazes you, you tend to ask less questions and marvel in the "coolness" factor.
Kool aid sells product and generates buzz and excitement. There are plenty of great things about kool aid. But there's a danger about it that I've come to realize over the years -- and it's directly related to how features themselves are marketed. Adobe is usually very good about showing you new features and cool technology. They pick a workflow or an example and say "here's what you can do!" and you stare at the screen (or stage) with your mouth open and say "holy #$%!" I need that. But let's say that the item they are showing doesn't interest you? Then you say "well, that feature is worthless to me - I have no use for it". And that's where it all heads south.
There are some features in Illustrator that have a certain pre-determined use, which exists only because Adobe marketed the feature that way. And in doing so, many people overlook those features because they don't realize that there are other ways the feature can be used.
In recent Illustrator history, I can offer two classic examples of a feature that was marketed in one way, yet the feature itself has far greater potential. These are 3D, and Live Paint. Sure, at face value, these features seem useless, or "not for me" -- maybe even a "yeah, it's cool, but come on -- I would hardly ever use it".
I'll admit that when I was first introduced to Live Paint, and I was told from Adobe how to use it, I was like "oh, this is dumb, it's so far from what people really need". Then one day, while fooling around with it, I realized just how powerful it was. I was looking at it (and using it) from a completely different angle -- the angle that Adobe was telling me about. Now, I use Live Paint daily -- I hardly use Pathfinder anymore. It's changed the way I think about building shapes and working with artwork. All of this because I drank the Adobe kool aid -- which blocked me from playing with the feature on my own and deciding for myself what it could be used for.
I see similar issues with 3D. When I talk to folks about the feature, their first response is "I don't do 3D graphics" -- but after showing them a few things that I could do using 3D, or artwork mapping, they flip out.
Bottom line is this: don't believe what the marketing folks tell you about features. Illustrator is a powerhouse that is there to be exploited. I define a power user as someone who knows a feature so well that they can use it for cases when you wouldn't think you would need it. So take my advice, drink the kool aid, but in small doses -- look beyond the face value of a feature -- you'll see that there's a lot more power to work with.
