* TV-Out now supports interlaced signals, making it possible to play the PSP games via S-Video to an older TV.
* The window viewing has been improved
* A microphone was installed
And that's my comment on the new PSP model:
The casing is virtually identical to the 2004 model. The built-in speakers are still atrocious. Who wants to listen to music, it is essential to use headphones. But it sounds good. The Internet browser is still a little weak in the chest. And the software keyboard makes when entering a nickname and Passwörten still STUV W * ß = # - A- EFG-H- KLM N QR-S- efgh-I- KLM KLM N-N- efgh-I- def G =) On the other hand cost handhelds that make everything better, still more money than Sony's gaming device. As such, the PSP is still competitive.
The new feature with the interlaced video signal is nice for people who want to connect the PSP to an older TV, but I find the feature anyway not particularly meaningful, since the graphics on the TV due to the scaling affects significantly blurred and the Games in the TV mode have an input lag, making it pretty much impossible to play, for example by Patapon. The feature is so Imo quite unimportant.
The new screen untersützt an extended color space, which makes the colors look a bit fuller. And he soon response times. However, I have to say that the difference from the model 2004 screen fairly low. That's why you really have to not change the model. The screen is worth my opinion is not the speech. I also have tried it in the blazing sun, because he is supposed to cut here well. Nope! This screen also has a very dark and pale with scattered light from outside. I would also use the Model 3004 is not there.
Then would be the built-in microphone. It can use with Skype (voice only) and with Go! Messenger (language + video, if you own a PSP camera). The built-in microcomputer is certainly convenient because you only have a small in-ear headphones need to make phone calls. One can theoretically make calls with the naked PSP. However, that causes the interlocutor an annoying echo. For online games, the built-in microphone is also quite practical.
Conclusion: The difference between the PSP 2004 model and 3004 is very low. Who would not take advantage of the additional features, with a clear conscience can buy the older model (cheaper?).
