I develop with micro's ranging from 128bytes sram, 2048bytes flash, up
to arm soc's with several gigabytes of flash and hundreds of megabytes
of sram, complete with OS.

I personally prefer the smaller micros because they are challenging,
and provoke a different kind of thinking than if i were to use a
soc board with an OS. Large and small each have their own application,
and reasoning. Sometimes limitations can be a source of inspiration
and allow us to find solutions to problems we would have never known to
exist otherwise. Likewise, the abstraction of larger devices should not
be avoided either as it teaches us how to implement and manage a complex

In short, I highly recommend that everyone own, use, and contribute to
both large and small devices alike.
