I can see where he is coming from. I own a DS Lite and an iPod Touch. In a year or so I will have to choose between the 3DS and a Touch 4G when the batteries on these two go south (and DS games become unavailable). The 3DS adds 3D and will be $250 to $300. The $300 iPod Touch has 32 GB of storage, a browser, good music and video playback, apps outside of gaming (e-mail, weather, news, skype) and id Software as well as Epic Games have been showing off game demos on the platform.
Meanwhile Nintendo has added 3D, which is hard to comment on until I can get one in my hands. 3DS has very little storage which means it won't replace the iPod for apps, music, video, etc. Finally, the highpoint of the DS is the games and I have not seen anything that I haven't played four times already coming out for this(I own Ocarina for N64 and WiiWare, have like a billion Marios, am tired of Metal Gear, etc.).
Part of the appeal of the original DS, at least in my case, was the gap between its price and that of an iPod Touch or iPhone when it first came out. But since getting an iPod Touch it has won the battle for the spot in my pant pocket.
