DualDisc: Less for More?

I read an interesting article on the limitations of DualDisc, and the short of it is that both the CD side and the DVD side have less capacity than their standard counterparts. They have only 60 minutes of CD audio, and the DVD side has a single layer like the kind of recordables you can currently buy (DVD-5). In addition, Denon has said not to use them in their players until they can do thorough testing. I was considering picking up the Keane DualDisc, then I found out the limitations forced them to drop a track on the CD side! Luckily, they also offer a SACD, so I’ll be going with that. It’s a shame there’s so much marketing behind an inferior product, they seem much better off just including a bonus DVD with CDs to avoid the mess.
