Call it whatever you want, the point is, it's plain silly for any total noob (who is not stinkin' rich) to spend $3500 on a piece of equipment they haven't the first clue how to use, when it is entirely possible to learn all the same ropes using a product that costs $500.
Why is it plain silly?
If the sole goal of owning the camera was "to learn the ropes", then I agree. $3500 is silly when it can be done as well for $500.
But if they are going to buy a $3500 camera to take pictures, it's silly to buy an additional $500 camera to just put up on the shelf once you've "learned the ropes", when you can learn them just as well on the camera you are going to eventually buy regardless.
Obviously "available budget" is always an issue, but I touched on that.
Then, if they end up sticking with it (which is not a foregone conclusion, I don't care how determined they think they are to be a photographer), they can always upgrade to something better once they identify what specific equipment limitations are preventing them from taking the kinds of photos they want to take.
Hence "Trial camera". It's only silly to start with the 5D if, in fact, you don't stick with it (or never need a 5D).
My trial camera was an XSi. Next camera will be the best I can afford without stepping into features I don't need (which given that I've got Canon glass, will likely mean a 6D)
I agree with you that the semantics are not terribly important; but I believe that your first paragraph, without the caveat of your second one, is wrong. BTW: There's a second caveat that would also support getting an inexpensive camera... not knowing which features are important. Playing with a $400 and kit lens starts to let you know which body sizes work for you, and how much you care about frame rate, and what lenses you actually need, before you invest many dollars in the *wrong* thing.
Would be horrible to buy a 5DmkIII and some lenses only to discover that a micro 4/3 would better suit your needs.
