Not for sure if this is the correct place to ask this but here goes. I'm going to buy a new Samsung and have been looking at the various models. Had decided on a 850 until I saw a chart that listed the specs for all the series they make. The 750 appears spec wise to be the same as the 850 except for the thickness and the swivel base, and can be had 300 bucks cheaper. Is there a difference between the 750 and 850 that I'm not aware of to make me spend the extra bucks? Thanks for the help, newbi here.
