So now that you've argued AGAIN about the whether the Wii is a gimmick or not, and its lack of 3rd party support how about what Sony has learned?
I don't mean to sound however that sounds, but do we really need to hash out old arguments with Ian? He's not going to be convinced, and he has some fair grievances, there's really nothing beyond that...
The PS3 is doing okay, and it is helped by its Blu-Ray player, which also helps Sony. All of their consoles have pushed a new, or burgeoning media format, and did so succesfully.
They tried to recreate that magic in the PSP and UMDs and failed. The PSP was/is marginally successful, but it failed on its mission to make UMDs popular, which would have in turn made the PSP popular. Now with the NGP they are moving over to digital downloads, and in an iTunes/App Store world, digital downloads is what it's all about. As Apple has already done it, Sony can't make digital downloads popular (I know mp3s and Napster were around before the iPod, but the iPod, then iTunes, and now the AppStore, made it mainstream and introduced/duped people into buying digital products they would not have with Apple's insistence) but they can ride the wave.
Also, the NGP is balls out powerful. If Sony has any sense in them, they'll encourage Kinect like hacks of the device and let people explore what can be done with quadcore mobile power. With phones and tablets becoming more powerful and going dualcore, Sony could have a marketable advantage in the competition for mobile users.
As for the 3DS, I think it will make 3D more popular, and in turn make itself more popular because of the ease of access and friendly price (compared to other 3D products).
