I care because Stern are the market leaders and in all essence ARE pinball today. Having loved pinball for as long as I can remember and having owned games from the 30's right through to the 90's I have a vested interest in the way the game evolves, as does ANYONE who is into pinball. So when we get a hype of "all new magna slings" I am very interested in the new developments and can see great potential.
But.. and heres the crux Pete.. what we actually see is a lack lustre product. Those slings have more dead spots than a friggin grave yard.
So now with Stern we have pop bumpers with a controlled release through a gate and slings that have the "all new slide action wipe with random no action".
Do I like it?..LOL - you decide.
Do I have to be a buyer to cast a critical eye?..NO
Do I have to justify that opinion..NO... but just for you... I did.

Well said mate. Stern have always been a reactive follower who don't take opposing viewpoints all that well which is probably why they appeal so much to certain personality types.  

Kudos to them for giving a new product a shot, but you can't release what is in essence a $10,000 plus prototype onto the market and not expect feedback.

As it stands it will take a lot of improvement for those magnaslings as they are to reach the level of traditional mechanical slingshots.
