Look, the iPad might be better for web browsing, general apps, etc.You do realize that the NGP is technically still just vaporware right? The thing isn't production ready for a reason, but I wouldn't just assume the specs are going to stick because you want them to.
Lest we not forget the original specs for the PS3... The model they had when they announced it had two HDMI ports, three Ethernet ports and six USB ports and that funny boomerang controller...
As for the chip being released in 2009... Just because they made a piece of silicon doesn't mean it went into production then.
Intel released this 80-core cpu a few years ago: http://techresearch.intel.com/ProjectDetails.aspx?Id=151
I STILL can't buy one.
There are no devices shipping with Quad A9 atm, heck, the Dual A9s are just starting to show up.
You also seem to not understand the negatives of such technology. 4 cores WILL use more energy than 2, it will generate more heat, and it will require more memory. And while you have mentioned how the device will cost less, there really is nothing to confirm that.
One of the few announced Quad A9 SoCs the Tegra Kal-El is slated for a 2011Q3/4 release.
The point is you are comparing a prototype to a fully function now available to purchase device. I'd bet you anything there are some scary powerful iPad 3 prototypes lying around apples labs that would put the NGP to shame...
Also, keep in mind that even if the NGP manages to launch before Christmas, and it manages to keep all the features they are claiming, and sell for a semi-reasonable price, there will only be around 3 months before apple is out there releasing the iPad 3 which if it has the specs that have been rumored would fairly easily beat out the NGP in most every way.
Quad Core isn't 1 year ahead of current tech, but it is around 6-8 months ahead. Announcing a product that uses parts that don't exist yet is easy (The original Electric Car lol) Bringing it to market is not...
But don't even bother trying to argue that the iPad 2 comes close to the PSP2. Touch controls are a joke for most kinds of games. Meanwhile the PSP has both touch controls and a complex arrangement of physical buttons. I still prefer my PSP1 over any iDevice for that reason (the physical buttons, that is.)
Then you have to take into account the games. The best the iPad has is stuff like Infinity Blade, Modern Combat, and Real Racing 2 HD. Yeah, they're neat. But do they really beat SOCOM, Metal Gear Solid 4, Resistance, LittleBigPlanet, Gran Turismo 5? The answer is no.
I saw a demo of a PSP2 running Uncharted and Metal Gear Solid 4. A handheld device, running MGS4 with PS3-like graphics. That alone makes it worth buying, in my opinion.
