I don't consider Android/iOS to be true consoles, and definitely not true competitors. I have never walked into a store and looked at the 3DS and said "Nah, I already have a smartphone." I can't imagine anyone putting $250 on their desk and saying "Hm, should I use this to buy a 3DS or a smartphone?" If you bought a smartphone, chances are the 3DS wasn't going to change your mind. If you have a 3DS, chances are you'll be getting a smartphone in the future, irregardless of your purchase.
Smartphones just don't have the inputs required for video gaming. It's definitely great on a bus or before class, but that's about as long as Angry Bird is going to hold my interest. And belive me, there's a huge difference between Angry Birds and Uncharted.
As far as how I feel about the NGP, I think a $250-$300 price point will make it extremely attractive. People need to realize that not only does the NGP have outstanding controls, it also uses the internet. If Sony can nail a full functioning browser and couple it with their supposedly sensitive multitouch screen, the NGP becomes a 5" tablet. Now we have a device that not only plays deliciously beautiful graphics, but will do everything a Samsung Galaxy Tab and iPad can do with a significantly more powerful processing unit and a smaller form factor (though this may or may not be a good thing depending on what you're doing). Considering the fact that the Galaxy Tab is $350 and the iPad is a whooping $500, $250 would be a steal for the NGP.
