I think its cool, and a great marketing move by Nintendo. The quality is much better than virtual console, and you get this cool little mini NES, with actual working buttons and retro controllers. That said I won't personally get one. It's expensive, (not super but its still a good bit of money) and I don't have the money to spend. I also have an Original NES already. I don't have 30 games, but I still just like the idea of being able to buy more for it instead of being limited to only the pre-loaded 30. I think its cool and great, especially for kids who didn't grow up with the NES, to enjoy some old classics.
It has some Pros over the original. It won't have near as many technical difficulties because of newer electronic technology, is smaller and more portable, and is cheaper than getting a real NES and all those games. On the con side, its not the original and you don't get the satisfaction of putting in actual cartridges, you can't get more games, the controller cord is long, and it is really tiny, though that could be a good thing.
So Personally not for me, but I still think its great.
