Summary: This TV has a cheap, flimsy stand, terrible sound, a washed out picture that is nearly impossible to tune with any precision and lacks all current features of mid-high end televisions. It's not ultra-slim, no matter what the description says - my 5 year old LCD is nearly as "slim". Once I finally got it calibrated to my satisfaction (still wasn't happy with the final result...) it looked sub-par on other devices (i.e. PS3 vs. 360).
Summary: Unit purchased Christmas, 2012. Worked about 3 weeks then began to power off sporadically. Sometimes would restart, other times needed to repeatedly power on. Problem became progressively worse. Net research suggested this was a common problem (either power supply or main board faulty). Contacted Samsung customer support. Their troubleshoot process a waste of time. I requested service call which went smoothly.
