copied from the 750 thread:
* 750 has an integrated woofer
* 16-bit processor vs. 12-bit in 650 (10-bit panel in both)
* 750 has DLNA features (can stream audio/video/etc. over a home network)
* 750 can play video off of DLNA/USB flash drive. 650 limited to images/audio
* 750 comes with 1GB internal flash memory pre-loaded with HD pictures, games, recipes, and a few other things
* 750's controls on the bezel have a red backlight. 650's controls have no backlight
* 750 has a square bezel compared to the 650's rounded bezel
* 750 has a square stand compared to the 650's oval stand
* 750 stand does not swivel (contrary to Samsung's literature)
They use the same panel. Not sure what the 12bit vs 16bit thing is about. I saw a slight bit of color banding (maybe it was the source? i was looking the bbc logo with all the gradients on the planet earth blu-ray intro titles) on both panels so it didn't make an appreciable difference as far as color reproduction goes to my eyes.
