I agree with the majority of your points but need to point a couple things out.

1. Agreed, but the Wii took the motion sensing concept to a new level incorporating it into its business model and not simply making it a peripheral like Sega.

2.  Home button on the PSP does not have the same function as the home button the 360.  Home button on PSP allows you to navigate back to the main menu and not turn off the console, msg friends etc.  The same thing sure but a different concept.

3.  Agreed, but the point is that they are not the unsung innovators of gaming that has been stated on the threads I outlined above.

enough with this home button,since it has the same functionality that it has on the psp which was introduced at e3 2004 one year before xbox360 controller was showcased........

cell was not developed by sony alone,there were also toshiba an IBM in development..ibm designs chip so most of the job was done by them

sixaxis uses motion sensing but not in the same way as the wii remote,although i agree the added it after nintendo announcement,however it was also an excuse for not including rumble

and btw sony controllers are unique in design not immitating any other controller(design!!!!!!!!)

also if u look at n64 controller is like a spacecraft so they didnt copy it!!

as for online,dreamcast was first to feature that

And Sony does tilt sensing, not exactly the same as Wii. It seems quite different to me. And if it wasn't for these technological innovations, the Wii controller wouldn't be possible.

i find it funny people arguing over something so small such as the home button.

"360 has it before ps3, but psp had it before 360!"

what a waste of time

"Using discs instead of cartridges back in the early 90's wasnt innovative? Using discs that dont limit developers is not innovative?"

Sega Saturn would like a word with you.

 ps1 was the first console to use cd,if it wasn for sony back in late 90s we would still play games that used 64mb of memory and not games that used 650mb and games like mgs,crash,spyro,tomb raider,ff7,gt and a lot of others would never be created.....so yeah cd was quite an innovative idea

LOL man this thread is so full of Win :D

Lesse.

1.) Motion control was definitely thought out by Nintendo, but Sony's add on seems almost entirely different, and they serve almost entirely different uses. But sure, we'll go with your idea and say they were inspired by Nintendo.

2.) PSP welcomes you to the world of home buttons, in fact, it was even called "home" button on the PSP. Hitting this button while watching a movie or playing music, viewing pictures, on the internet, etc etc took you directly to the XMB, and hitting it while in game gave you the option to quit to the XMB. Sorry PSP innovation baby ;)

3.) Right, because online is an idea that had to be stolen /rolleyes. Hey how about this, if I'm older than you are, I'm going to go out on a limb and say you ripped off my idea of breathing. How dare you. Besides, think of all the companies that could benefit from an online store, does Sony ring a bell? Movies, music, games?

4.) Controller, Did you ever think that they did it because it ummm I dunno, worked? As far as I know Sony had 2 shoulder buttons before Nintendo ever did, they had the second analog stick before Nintendo ever did, they certainly had the home button before they did. I mean seriously, are we just going to assume that Nintendo and Microsoft ripped of Sony by including a second set of shoulder buttons? No, thats silly and ridiculous.

5.) Why god are you bringing the hardware into this? Nintendo used existing technology, Microsoft... used existing technology. At least the Cell is different -_-; And if they're under copyright infringement, so is IMB and Toshiba.

Soooo while were at making ridiculous claims lets throw a few of these in yah?

Sony popularized DVD media for games, therefore Nintendo and Microsoft must be ripping off.

Sony Popularized the use of Memory Cards, therefor, Nintendo, and Sega directly ripped off.

Sony's playstation 2 I believe was the first console to encourage movie playback on a video game system, making it an "entertainment system". Microsoft ripped off obviously.

As mentioned earlier, the popularization of a second analog stick, the built in rumble , and the addition of a home button I'm gonna have to throw Sony some bones here.

All in all, I don't care if they made or didn't make some of the technology out there, they are most certainly innovators for most electronic applications on the market of today, and if they took crappy ideas, and made them better, are we really arguing the innovation? N64's rumble pack sucked, Sony's d-pads are almost universally recognized as the best in the industry, and they did popularize so many things.

 so would sega cd

Whether or not the idea's are innovative, it's the use that Sony put them to and the way they perfected them to their needs.
