Rooting is totally optional and not a must. Yes, it will void warranty stated by Samsung and other manufacturer warranty policy.

You can enjoy android without rooting. If the application is not available, there is other way to get it and side load into the android.

I own SGS and SGA. Stock to stock comparison, the experience is same. Unless, your SGS running custom ROM and Kernel but that a different story altogether. Only 3D part is different. PowerVR 540 graphic proc is still the king for single processor android phone.

SGA still retain RFS file system but the speed is equivalent to SGS running 2.2.1.

Two touches.

Yes, you can do multi touch operation. Even HTC Desire is dual touch. The only setback, you can't play certain game effectively (if it required the third touch laaa)

Got

It shows currently consumed RAM + Available RAM. You should not worry too much on the RAM part, Android will take care of it and kill whatever unnecessary apps to make room for foreground processes.

Are you using the stock video player to watch the video? You can try rock player (market) or moboplayer (google please), see if these app can play the video first.

You can try built-in screenshot feature, Back button + Home

No prob, but the built in may have some problem in certain app. Good for someone who did not root the phone yet...

Nope, only DLNA available.

It is not "in this phone", it is how android works. The back button will do either these three things if you press in any applications....

1. Minimize the app or
2. Ask for exit / quit conformation or
3. Act as back button or
4. Quit the App

Android will take care the RAM management. I rarely use task manager except to kill problematic app.

Digital Livingroom Network Access.... the "All Share" app in the Samsung.

SGA Samsung app looks like an app for update only IMHO, not like the one in SGS. If you browse to Samsung website, it stated like what I mentioned.

Samsung stickers and e-warranty (notification of warranty status thru SMS).

Yes, do it before handing over the cash. Compare it with the box etc.

I got it at 900, some owner even got it at 890.

There are taking advantage on the demand

Press and hold back button + home button. But if rooted, better use app from market like shootme

Yup, only some app work with this method.
