Pros Picture quality
USB (Play's movies)
Channels availability with out an actual cable box
Cons Remote control can be better
Only 2 HDMI's
Summary I purchased this TV last week and this is my initial assessment.
Nice picture quality, design, sound not bad out of the box, good size for a bedroom, only 2 HDMI's and the features I Like the most is that I can play my Movies through the USB connection including avi's, no need to get a Blue ray with USB that can do that. The other feature is that is only connected to cable (Optimum online) with out a cable box and it gets a bunch of channel and many of them in HDTV.
The remote control itself is not bad better than some that I own but it can be better. I would like that the main buttons glow in the dark in fact not just for this remote but my other one's too.
I initially encountered the issue mention in the other reviews with installing the screws in the stand's mount, I switched to the other set (There are two sets of 4 screws) they never got 100% down but down enough to be stable and that seems to fixed the problem.
I suggest you have to check for best deal before you buy this TV at: Cheap-hdtv-suggestion.blogspot.com/2011/11/ln32d450.html
Hope this helps.
Pros The brightness level, sound, pc connection, very user friendly, easy set up.
Cons The stand need better threading for screws, leaves the stand slightly off center.
Summary This is currently the third Samsung in the house. Love everything about this set, will be getting another some for the gym.
