Up until your last two paragraphs, you seem to have confused your subjective opinion with objective truth.
Not really, surpisingly enough. It's a fact that sunrods make other sources of light pointless and make tracking lighting pointless, and that's my main objection to them. Even people who like sunrods agree, to whit:
Sunrods light a large enough area that you shouldn't have to worry about lighting effects while you have one out. This is a Good Thing.
It's obvious, I think, that drothgery is correct in a sense, in that D&D's designers believed this was a "Good Thing" (I've been saying this all along) and it fits perfectly with 4E's "don't bother with the boring" design philosophy. However, if sunrods are going to be so powerful, they should have either dumped or altered other light sources to compensate, particularly magical ones.
I can respect that people like sunrods for their games, but I think they're a bit much for a default part of the gameworld. Not that Continual Light wasn't, either, but hey, I remember house-ruling that thing's radius down too and it got the chop in 3E. I do think they fit well into the Epic tier, however, and I might reintroduce them for that.
I do admit being personally offended by the lameness of the term "sunrod" (also rofl), but even if they were call "magic lanterns" or whatever, the radius and price would be Just Plain Wrong.
Edit - I'll give it one thing - at least it doesn't produce any "shadowy illumination"
