"Does anyone buy on the basis of a product showcase?"
Hell, yeah!! 

Quote - I suppose I am meant to think that "all this will be yours if you buy Vue 7", whereas I'm thinking "You'll never be as good as that, so don't kid yourself".

LOL! You are not alone!  Both viewpoints go through my head when looking through any software's marvellous promo renders! I initially go through my "OOoOooO! Shiny!!" reactions; but then I think, based on my own slow progression, "By the time I get there, we'll be rendering holograms!"

But be encouraged, my friend. With dedication and time, we can only improve!
