And if HD-DVD is so great, how come more studios are behind BR now?
Key word here is more. There are three big studios still supporting HD DVD. Take out the SONY studios from the BR camp and you end up with HD DVD having more studio support and it doesn't look so rosey. It's not a mystery why SONY supports BR. OTOH BD-J vs iHD demonstrates a complete victory in favor of iHD not some indecisive 40/50 standoff.
You claimed iHD is technically superior to BD-J. It is not, therefore you're wrong. Now you want to change your argument and claim that the features of BD-J are not needed. Well, that's a different argument. It's like saying that 25Gb isn't need, and all you need is 15Gb. Unfortunately, it wasn't your original argument, where you tried to pony off a list of supposed "superior" features in HD-DVD.
Actually I said HD DVD has become technically superior and listed iHD as one of the features that make it so. I didn't say iHD is technically superior to BD-J hence my light bulb/wrench analogy. In fact I said BD-J is more complex while iHD gets the same requirement done with less effort. iHD is superior through elegance and simplicity.
