Let me start out by saying that I too have a 360. I love it. I love using Windows media 11 to stream music and pictures to my HDD, and XBL is amazing. Obviously I am a fan of Sony, except audio, as well as Blu-ray, because I feel that it is a better technology and will last longer into the future. The extra space will help with a number of problems currently facing developers and movie studios.
To answer your questions.
1. Sony has not released full-spec sheets as of yet for the PS3. But, this I do know. The PS3 will have
256MB XDR Main RAM at 3.2GHz -CPU
256MB GDDR3 VRAM at 700MHz-GPU
The 360 has
512 MB GDDR3 RAM @ 700 MHz DDR (SHARED) using a unified architecture to share the memory with the GPU and CPU. The custom ATI graphics allows this to happen.
The 360 is sharing its ram with its graphics card, much like the way a computer with an on-board graphics chipset works. The PS3 has 256MB of RAM set aside to the GPU as well as XDR ram which is supposed to be 12X faster than GDDR3. In my opinion it seems the PS3 has the performance side won with this.
I don't even think it's fair to compare the Cell to an IBM power pc based 3 core CPU.

I am assuming that you want screen shots? If so here is a link to Gamespot where they have screens for all the games and are high quality captures.

Yes it is free. No gimmicks. The only thing that you have to pay for, if you want them, is PS1 games. Also new maps and additional features to game could come out and will be priced from a penny to two dollars. But TO PLAY THE GAMES YOU PAY ZERO! Demos are supposed to be free just like XBL. Gamerscores will be on a game by game basis, Sony will not make up an individual one. All you pay for is additional content.

I know that right now HDDVD is the biggy. People like the PQ better, and they all seem to absolutely hate Blu-ray. IMO Blu-ray is needed, not necessarily at this moment, but within the next year and a half I feel it will be extremely necessary. With the extra space, devs will be able to go about developing in so many different ways. They can use less compression on games, give more levels to us, and provide more than 6 courses on a Tiger Woods game.
I have very few problems with my 360, and I do not hate it, nor do I hate HDDVD. I just feel that Blu-ray is the
supreme technology and will be needed down the road. Everyone has always said that we don't need any more space. All the big players in the industry since Bill Gates comment that we wouldn't need over, what, 512k memory have ALWAYS been wrong about space necessities. I'm using history as a basis for all of this while it seems other people are using fanboism to an extreme. If HDDVD wins I wont really care, I wall always think that Blu-ray was better, but I will still buy the disks and such, so in the end it doesn’t matter to me.
How does that translate into the PS3. In my opinion more more more. I can see so much more coming from the PS3. So many levels, weapons, playbooks, etc. that DVD9 is just too small for. EA has said the reason Tiger Woods has so few courses is because of space restrictions. In this era of gaming I believe the extra storage space for the PS3 will be the major winner. Both systems are
comparable hardware wise, but I believe the PS3 notches out on top slightly. There is so much more that I could get into, but I am slightly tired right now. So I hope this helped you make a decision.
