I'd agree, I would have thought it would be best to go for a entirely
I think your problem is accommodating different users with different
1. Hobbists, using the gumstix for fun.
2. Companies/Academics using the gumstix for development/prototyping.
3. Companies/Academics using the gumstix as a component in a product
,perhaps for short runs.
Users 1&2 are going to want everything on the gumstix, size will be an
issue but as long as it's portable/pocketable which the current size,
and even a little larger is, I think they'll be happy.
Users of type 3 are going to have widely varying requirements, but could
be your best customers.
My suggestion would be to make the base gumstix board as small and cheap
as possible, which would hopefully decrease the design complexity and
let you get it to market quicker. But also design a versitle modular
upgrade system, so that if people want to add breakout boards, audio,
wifi, USB2 host, etc. etc. they can.
That IMHO would be a killer product.
...but then I'm a hobbist/academic user so, put everything on it. :)
enough random rambling from me,
