Not silly at all for those who bought 1st Gen DVD+RW drives back in 2001 
with the promise of DVD+R compatibility.
As I said, Sony/Philips has falsely advertised again and again and again 
- all the way back to the old 3GB Japan-only DVD-R+W.
I don't see how people can defend them.

The only thing I can think of is that people often confuse DVD-R(G) 
standards from the DVD Consortium with their CSS and Video standards.
Two whole different ballgames.

No.
It meant by 2004 consumer electronics could handle MO technology more 
reliably.
It had *nothing* to do with "maturity" of DVD+R, and everything to do 
with consumer devices being able to emulate pie-slice MO as a single 
grove like ROM/WORM.

I urge you to read up on the *physical* differences between MO and 
ROM/WORM.
A MO pie-slice media must be emulated like a ROM/WORM single-grove by 
the end-device.
It's like trying to get an analog record player to play a hard drive.

And that's just the compatibility, not even looking at longevity.

The funny thing is that Matsushita DVD-RAM has had better compatibility 
on licensee's drives than Sony/Phlips DVD+RW did in the early years.
And DVD-RAM was never designed for consumer use, but optical archiving.
