How can it have two quad-core CPUs?

You don't seem to take yourself TOO (there's a hint right there) seriously so no worries man

Is the PS2 GPU much stronger than Tegra 2?

it's got a 4 core ARM CPU and the GPU design they are using (same as the iPhone) has 4 "cores or at least that is what the designers call them. http://www.techradar.com/news/gaming/consoles/inside-the-sony-ngp-the-cpu-and-gpu-in-detail-924306

You didn't read my post on page 1 :(

Thing is you don't have even tear drop of technology awarness

1.First of all PS3 done have 2x Quad-core CPU, it got single Cell processor that is single-core CPU supported with eight SPEs cores, that untypical architecture is reason of PS3 being told that it's hard to program, since it's need heavy multi-threading to be bale to use it's full potencial. But putting that aside, portable CPUs are made to be power economic and less heat as possible, also they got slower clocks. How PS3 get ported in inferior hardware, i got theory how they do that that anwsers also quastion number...

2. Game developer not programing CPUs or any hardware direcly, things liek that exits in 8-bit and 16-bit are when CPU machine code in form of assebler languge was in range of human understanding. After that higher languge taken over, like C/C , to control hardware APIs was made by the hardware developers. APIs is set of easier functions ,something like simple function activating other code this is more complex, that for example can control hardware.  API can be replaced to be use in other hardware, but higher code that using that API don't need to change at all since name of functions not changeing. What im saing here (and thats my theory) what Sony did is to make NGP SDK APIs very similar to PS3 APIs, allowing to speed up the porting process. But here one thing, what you see on videos is not so butiful as it is in PS3 in detail, it surly infarior graphics that you need to watch it closly to see the diffrence, most visble on demos was lower resolution shodows (causing chopy shape of them). Even if this look like PS3 power, it isn't, graphics are lowered down to power of NGP.

3. Flash memory is have ability to write and read..... yes write and we don't need that to game medium. Insted of useing Flash Sony can use some kind of ROM that is programable only once and is cheaper in production then flash memory, same tech that Nintendo using

4. anwser on quastion 3 solves that

5. You bet, that what developers liek the most... not kidding.

6. Execpt communication (that you anwsered yourself), cameras allows for Extender Reality games, on front camera it can involve  face to that. But for develop it's not mater it's just input device that can be used in some way, for example for quick pic of you face that can be used in game.

7. I don't know :p keep in mind PS3 still have similar sales to cheaper 360

8. PSP is most succesful non-Nintendo portable console ever made, lot of portable manufactures would sell there soul to be in Sony's position right now and, throwing this out would throwing golden fish without saying the wishes. Look other portable console trys and compire this to PSP. Also look on stationery consoles, PlayStation kicked Nintendo back-parts sky high, did Nintendo resignate no. Xbox was also not much of sucess, did they resignate? No. You won't build postion without trying.

9. Yes and no. If NGP will run android, it will run Android apllication that is writen in Java, Games on other hand are made in compiled in native hardware code and won't be able to run it on other hardware then NGP.

10. That quastion is nothing more they joke :p

So is it like 25% faster than an iPhone 4 or is it magnitudes more powerful?
