I think the manufacturer will be biased on marketing a new machine. After all, they want the sales, it's new. If they compare it to their previous top of the line, they are not going to talk down the previous, just add what the new machine offers, if it's more bells and whistles, or something functional and affordable. Then it's up to customers to choose.
A car manufacturer offers several models - customers choose. Some want all the bells and whistles, others go basic. Nice to have a variety to choose for the folks out there.
I got interested fast on the Vision. Normally I would wait months on a new market product to get both biased and unbiased views. Then wait in part also includes any bugs unforeseen at the start. Most things that caught my interest, I'd wait typically 4-6 months to pull the trigger. But when it came to the Vision, from what I saw and what little I read, I pulled the trigger fast on it - oh, and my local dealer had the Vision available. The weather was spring like and the "I would like to try one" hit me suddenly. The screen with the color and additional informational tools - why I would like to try that.
So it happens. So now I have a small handful of machines from the single knob Tesoro Compadre to the White's Vision - simplistic no bells no whistles, to bells and whistles. They offer choices and I make my choices. My choices start from that it must be a major well known manufacturer & quality. Then things just go from there.
