I just bought this today, and the overview still says it's a swivel stand. There's no swivel in my stand. Who did you contact at LG?

The base does NOT swivel. You either miss-read the overview or the overview is incorrect.

In short, yes it is worth it. If you already know the difference between the two then I apologize for repeating what you already know, but the 120hz/60hz refers the refresh rate of the picture. In other words, a TV with 60hz refreshes the picture 60 times every second. 120hz is double that, resulting in a clearer picture as you are seeing more "frames" per second. The result is a less blurry picture. However, most channels broadcast at 60hz, so whatever broadcast the TV is receiving is what is going to show on the TV. (full disclosure, I may not be exactly correct on that, but I know that's the gist of it). But a blu ray on a 120hz TV will look far superior to that on a on a 60hz. Hope this helps you!

Yes you can. I have a WII, PS3, and a blue ray player hooked up to the tv and all 3 can support Netflix. You must have a wireless internet router from your computer to do this.
