You can't play Madden on the Panasonic and the PS3 does have very good processing. It's a game system and as a computer nerd I can tell you game machines tend to be more powerful than Home theater PCs not built for gaming.
I suggest a PS3 to anyone getting a blu-ray player. No other player offers gaming.
There are any number of reasons why people do not get the PS3 and don't want the PS3. I don't argue AGAINST the PS3, but hopefully you agree that people may agree with some/all of the points below.
1. The PS3 has no full IR control capabilities without extremely specialized third party products.
2. The PS3 has no IR control capabilities out of the box.
3. The PS3 generates far more noise than stand alone players.
4. The PS3 has a price point that is now a fair bit higher than the competing stand alone BD players.
5. A game system in the theater invites my kids to come play video games in the theater - this is not something I want.
6. The PS3 is far more complex than current Blu-ray stand alone players which may present reliability issues.
7. My equipment rack is not well ventilated, so I can't have the extra heat which the PS3 produces.
8. I'm not totally green, but I don't want to draw all that power to run a PS3 when all I want to do is watch a movie.
9. Movie player. That's it. That's all I want. I don't want a silly looking game system in my rack.
Yep, I've pretty much heard all of those in my dealings.
Personally, I want a stand alone player because I don't want all the wear and tear on my PS3 for movie watching. I'd rather use it for gaming, and leave the movie playback for a movie player. Still, I've already got my PS3 which I've had since release date and have been very happy with. It certainly is a very good option.
