i have the exact same dilemma. i ended up with these 2 LCDs, help me too. according to the reviews this is what i concluded.
> sony w650, the blacks are not as deep as the samsung f6100.
> the PQ of sony is better than samsung but only the HD videos.
> there is pixelation while viewing SD videos( most tv channels) on sony. samsung seems to be better in this case.
> no 3d in sony ( i dont think this is a prob for me)
ps: sony w650 looks cool even when switched off. i kinda like that.
so what do you guys think ? which one should i go for ?
