Well, it's ignorant sure, and definitely a backhanded compliment, but the casual user really does think in those terms. Basically he's just saying that it is in fact strong enough to actually play the types of games that the newer gamers care about.
IE graphically intensive shooters and sandbox games.
Now I think it's sad that most gamers experiences nowadays are limited to these genres, but acknowledgment by the masses of this capability will be the thing that REALLY lets the 3DS dominate. They already have the casual in the (blue ocean sense) gamer locked up between price, Nintendo's understanding of that market and previous DS experience, they will be successful with the hobbyist gamer, as the first party Nintendo software as well as the big Japanese developers games will be must have purchases with this group. The last market to really penetrate are the "other" casual gamers, the ones who really only buy a few titles per year, similar to the blue oceaners, but are much more enthusiastic about the titles that they do buy, and tend to use the software more frequently. These are many of the Halo/COD/GTA crowd that are such an important factor in the US.
These users would have avoided the DS, not because they didn't think that touchscreen was compelling, or because they dislike nintendo, but because the hardware simply wasn't able to deliver a faithful enough adaption of the game types that they enjoy the most.
It's possible that the salience of the 3-D technology conflated with the hardware capabilities and apparent improved software approach will allow the DS to reach heights in america that the DS was never able to achieve.
The PSP had potential to do this last gen, but suffered from a variety of well known problems, and didn't have anything like 3D that will (warranted or not) capture the attention of impulse purchasers. Why buy GTA, COD or Madden on the PSP if it's the same thing but worse as the console version? 3D more than anything else offers the 3DS differentiation from anything else on the market. It's a way more easy sell to your average gtacod enthusiast to give them the chance to play their favorite games in CD than it is to just sell them on playing an inferior port.
The 3DS is going to sell like nutbusters, and if they secure the types of games that american gamers tend to buy in droves it could spell death for the NGP before they even have a chance to launch.
God forbid the 3DS becomes the monster hunter lead platform in japan, because on the software side that is really all that it has going for it from a sales perspective.
