I don't want to turn this into a forum for next generation development software for the 8051
No need to worry about a discussion about cows flying over the moon.
The fact is that the '51 is intended for applications where hardware cost is important and thus so called "advanced software generators" have absolutely no purpose in the '51 world.
No manufacturer in his/her right mind would develop products for the '51 that only amateurs (who, as we have seen, will not pay for software) were interested in.
