I think there's room for both. Zenonia was a good iOS game that made its way to DSiWare. Same with Cut the Rope. For the right price, I'd take a paid version of a game with better controls.
Also, Nintendo really needs to allow FREE content in the eShop. Not just videos and video apps, free games, demos, etc. The only exception(s) to this rule are Pokedex 3D and Four Swords Anniversary Edition (free for a limited time).
Did you not read what you just posted? Because you pretty much said we're idiots for buying something most of us know we would enjoy. I'm all for new experiences, but I hadn't played Super Mario Land 2 for more than fifteen years, and it was one of my favorite Game Boy games. If I'm wrong for buying it and not Escape Vector, like you're implying, then I'm happy to be wrong.
If Nintendo at least had a better online store, more demos, an easier way to access said content and manage it, maybe I'd buy more WiiWare titles but as it is now, I rarely turn on my Wii because there's really no reason to.
Same for the 3DS right now. It's rarely more than a glorified pedometer.
