Wii Yoga is a neat concept in terms of how they do it.
I'd say both sports can be flowing, and modern snowboard instruction takes a lot of the hard falls that people used to take as part of learning to snowboard out of it...most of the time. You probably are still more prone to take truly jarring falls on a snowboard, but less prone to injure your knees while doing so.
As far as skateboarding goes, if you are familiar with longboard skateboarding -- the kind you see people using for transportation on the street -- that is probably more accurate for what snowboarding is like, assuming you don't choose to do things that make it more like the "trick" kind of skateboarding you see in skateparks.
If you're already comfortable on inline skates, you're probably going to have a shorter initial learning curve on skis. The residual greater risk of another ACL from skiing, relative to snowboarding, is a tradeoff.
