I bought an LC-60C6500U (different from the 650U? ) at Costco on Friday for $1150. (They extend the manufacturer warranty to 2 years, BTW.) My reactions are similar to many - nice picture, glossy screen, nice small bezel, etc.
Regarding the much ballyhoo'd dual core processor, I will say that compared to my LG 46LD550 and 60" Aquos 79U, the menus are a lot snappier. Further, when I launch Hulu Plus using WiFi it loads a LOT faster than Hulu doeson the PS3 and Xbox using Ethernet. Clearly it's grinding through that program very quickly. Regarding streaming apps, even using WiFi, the buffering is minimal and picture quality is very stable.
Speaking of the PS3, it can be controlled by the tv remote for at least the PS3 home menu, Netflix, and Hulu Plus. The tv remote has a dedicated button at the top that will toggle the PS3 power, as well. When I switch to the PS3 input, the PS3 turns on automatically. Conversely, when I turn the PS3, the tv automatically switches to the PS3 input. Very slick. I don't remember testing if powering on the PS3 will automatically power on the tv. The X360 and WiiU don't have this functionality, presumably because they are not Blu-Ray players.
There is a quick start option that seems to be a sleep mode and is pretty close to an instant on ability at the cost of higher overall power consumption.
I have to use Game Mode for everything or the audio and video do not synch regardless of the source, even with the onboard Netflix and Hulu apps. My set is connected to a ten year old RCA tuner via optical cable, running a 2.1 speaker setup. It is a perplexing problem because my above previous televisions didn't have it, regardless of the settings. Adjusting interpolation doesn't fix it. The first thing I did upon first powering the tv was to turn the tv volume all the way down and I haven't changed that initial adjustment... and I didn't think to investigate the video audio sync matter with just the internal speakers before leaving town for the week.
Since the tv looks and works great in game mode, this is not a large problem, but I do enjoy the SOE and I am interested to hear of a solution to this... er, defect. I think I read somewhere that external speaker setups sometimes do that. The manual, which I read, didn't say anything about that that I found.
The screen glare is annoying, but the extra light the glossy screen permits almost makes up for the glare with a more vibrant picture and, to my eye, better black levels.
Bottom line, this seems to be a good value. I am happy with it.
