Amazing how angry some people get in a discussion like this. George, calm down
man :-)

My experience is that it reduces development time. We use C++ in an embedded
MIPS environment (lots of RAM) and have objects to abstract hardware but also
things like an IPv4Address. That may sound odd, but there really is no overhead
compared to using a u_int32_t and it makes working with those data types much
more convenient, which means less development time :-)

Well, yes and no. We are moving the 'core' functionality out of the product
and into a library. Other tools running on the platform can use that now. So
yes, there is a lot of reuse. Same way as you would reuse a libc.

What would you like to know?

I would like to have some benchmarks running on this board. If you have
access to the board I can send you the benchmarks or can put it on my
website.

It looks interesting, but I couldn't find the pricing on that web
site. How much does it cost in volume and Q1?
