Of course, but you mentioned " extremely expensive microlenses", implying that they are not the usual kind.Every sensor needs microlens and the Foveon is no exception, especially considering that it is basically three sensors put together - giving it more depth than your usual Bayer sensors.
I am glad you like it, and I agree that it is better than the average P&S. But the thread was about improvement, and I think there is plenty of room for real improvement, and Canon is just lazy about it.Overall I can't say enough positive things about this camera. Sure it would be nice if it had HD video or a higher resolution screen but those aren't required to take fantastic pictures.
