There's no way to put any definite figures on it. It's a trade off between
the cost of the Flash and RAM a particular piece of software takes up, and
the amount of value it adds to the product. It's also depends on what
alternatives are available with the features you need, plus if there is a
licencing fee you have to factor the cost of that into the equation too.

Probably not more than 2* in either direction. Roughly speaking, RISC
architectures like ARM tend to need more instructions to do a particular
thing then CISC architectures like x86.

Just generally try to do things in a compact, efficient way. If you're
faced with a choice between a fast, large way to do something and a slow,
compact way to do it, it's generally best to do it the slow, compact way
because at the moment at least, clock cycles are cheaper then Flash.
