Samsung LN52A750 Excellent tv with extra features

I bought this at Amazon 10 days back ($200+ cheaper than right now).
It arrived on time this Saturday. Perfect packaging etc.
I am using this as a wall-mounted TV in the master bedroom,
replacing an older 52 inch Samsung LCD which is going to a game room.

My Hardware Setup and Sources:

1. Over the air HDTV - the fishbone antenna is hidden
in 1-2" mounting space between the TV and the wall).

2. Roku Netflix player (720x480 via HDMI - DVD quality content),
which is connected to Ethernet router.

3. Second input from my Dish VIP-622 via composite.

4. WiseLinkPro (TV connected to Ethernet router),
streaming from an HP EX470 Windows Home Server running both
TwonkyMedia and a Samsung Media player (install CD came with the TV).
This server has HD content I have downloaded from On Networks.

5. Router: I use the SMCWEB-N wireless router in client-mode
which gives me 4 LAN ports locally, the router wirelessly
connects to my home wireless router in N mode.
This allows 1080p HD streaming - much better than wireless g mode.
This router is also hidden behind the TV in the 1-2" of mounting space,
with power cables running behind the wall to a shelf below.

6. I do not have external amp or speakers - rely on TV sound
as it is a set up for the bedroom.

Picture:

AMAZING.
My picture settings for the sources:
Dynamic, Backlight 7, Contrast 52, Brightness 47, Color 52,
Color Temp: Cool1, and other things as default.
The colors and resolution are jaw-dropping.
Regular TV (dish second input via composite) looks decent as well,
and Roku looks awesome.

Sound:

Much improved from the last LCD model of the same size. Has more depth,
and much improved clarity. Would not compare with actual decent speakers,
being housed in a TV cabinet and all, but when I stream music to it,
is quite acceptable for our needs.

Extras and Other Comments:

I upgraded the TV firmware from the Samsung website using a USB drive.
The remote control response became snappier - not sure what else it fixed.

The touch of red tint around the edges looks nice - matches walls with
in our case. Makes the TV look even more modern, but that is a matter of taste.

TV came with a bunch of pre-built media - pictures (Monet and van Gough paintings),
recipes, some low-powered games like bowling etc. There is a Content button
on remote to get to these.

The remote is nice. Feels a little big. Does not seem to have a sleep button,
you can get to that via menu. TV has Three programmable on and off timers
that can be set up by day.

WiseLinkPro is something else. HD streaming over the home network without external devices!
But standard TV streaming for some reason is a little jerky - like the speed changes.
That is bothersome, as when I stream the same videos to my PS3 it is silky smooth.
HD streaming is silky smooth, however. More video codec support will hopefully
added with future firmware upgrades. Not sure though.

Overall, this is the best TV (and much more) I have ever owned.
Got it for a great price from Amazon.
