Well, like Hand76's rushed "first impressions" post with his replacement IPS panel, here's my very brief first impressions post on my just-received NON-IPS (from Amazon) panel:
I don't have it in position in my entertainment center yet...just had time to put the base together and get it on its stand on the floor with an indoor antenna hooked up (NYC area).
Honestly (and this could be premature) -- I don't see the viewing angle problem that others say they have on the non-IPS panel (yet, anyway). And I'm coming from a plasma world where viewing angles are not a problem to begin with. Additionally, I work in network television. I went almost as far to the side as I could without seeing much if any loss of color/contrast. But again, it's not set in the position I'll be viewing it at. For now, though, I'm pleased with that.
The sound is much, much tinnier than I expected. I have to work on that! My Panasonic plasma from 2005 has much better sound, but then it has front-facing bottom-mounted speakers. That's going to be a work in progress. Yes, I do have a home theater setup, but I don't want to have to turn on the HT every time I watch TV!
The DTV tuner seems much more capable of picking up NY area DTV signals than my older plasma's DTV tuner. That's good to see.
OK, that's the nutshell. I'll give a more in-depth review when it's all set up and tweaked, etc. It's a DLHR coded-set, "Hecho en Mexico", as they say, in July of 11. 42" panel.
