I don't wanna rain on anyone’s parade here but this isn't really a runner
is it?
I can't talk for other territories but here in Ireland the mobile market is
mature and saturated with low cost Android devices. So much so that people
are actually upgrading now and selling their old Androids and iPhones. I
suspect the situation is similar elsewhere.
.... and thats just the new market, there's also a thriving second-hand
market were you can pick up an Android phone for €30 and throw on Cyanogen
Mode yourself. Plus the very group of tech savvy people who might be
interested in this are the ones who are well aware of these alternatives. In
short people have far too much choice already when it comes to smartphones.
While a fully free smartphone might work, if you keep the costs low and build
on a "build/buy to order" basis Dell style, its never gonna be mass market.
