Summary: I returned it today (no hassle with the return – Walmart’s great about that). I think this set is not the best choice if you want to use it for over-the-air broadcasts, which I do. I was not able to consistently pick up the local ABC, NBC, CBS, FOX, and PBS stations with a single antenna position (even with the special indoor amplified digital antenna I bought).
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).
