hi
i'm pretty sure there is a cheaper alternative then the version we
are having . i have some ideas and i'm if we think we find some very
good ideas - more cheap .
but ,
as i see it it's better to aim NOW to get the fast we could go with
what we have .
why :
1.because any design at low cost $150 / $50 will change the market
structure probably
2.my experience at projects - you have to have something in hand .
not optimal and then go to next version .
3.if we get first version at $150 - making the other versions
(lower costs , more capabilities)
would be a piece of cake because
1. interest in neurofeedback
2. the sucsess of our group (sucsess draws people )
4. focus in any project is important .
but still , the only way i can see maybe good for doing a second
version , is if we have a designer that can do that , and he
can't help in anything in the main project .
but when this point comes , we should talk , i think .
sincerly
yaniv
