You are 100% right about the effective halving of the frame rate when 3D content is displayed. Fortunately, 3D displays are required to support a refresh rate of at least 120hz, and some can even operate at 240hz. In the case of a 120hz set, each eye gets to see a 60hz image, which is the current HDTV standard in the U.S. (I think U.K. is 50hz, right?). This is also why we won't see games like God of War III supporting 3D on current gen hardware like the PS3, which couldn't possibly render 120 frames a second of that elaborate of world and character detail.

I think the use of the term backwards compatibility is slightly misleading. Even with dual analog sticks, the PSP Go! would be 100% compatible with any software (UMD format aside of course) released for the PSP platform. Sony's concern is that software developed to specifically take advantage of the PSP Go!'s dual sticks would not be compatible with all of the PSP hardware released prior to the Go! that lack a second analog stick (3000 series and earlier).

In other words, Sony doesn't want to harm the "early" adopters, they aren't worried about new or old software not being able to run on the new system.

You know, actually, I kind of take that back. I do use the PS3 browser once or twice a week to download some video shows off of Revision 3, CNET, and 1UP. I know I could just download the videos through the PC and stream it to the PS3, but it's usually a spur of the moment decision while I'm at my TV, and since you can start watching downloads while they're still in progress, it's ends up being a time saver. Kind of handy, but not for web browsing.

So, the PS3 has three people using its web browser and the Wii has two?
