Connectivity is a great feature to have in an HDTV or Blu-ray player. It allows you to connect to the Internet through your home network to do things like watch streaming movies from Netflix or YouTube videos or listen to your own "stations" on Pandora. You'll probably only find "wired" connectivity with Black Friday deals but if you can get wireless connectivity all the better.
While the world waits for more 3D programming and prices to come down, the standards are in place to support 3D content so a 3D capable TV you buy TV should still work in the future. You may not want to watch 3DTV all day long but it should be fun to watch the occasional 3D movie, sports event or rock concert. The same goes for Blu-ray players, you can future-proof a Blu-ray player purchase if the Blu-ray player supports 3D which means it will also have an HDM 1.4 port.
Known Brands and Longer Warranty
You may come across some great deals from manufacturers you've never heard of before. Taking a chance on one of these could be a safer bet if you buy it from a reputable reseller with a warranty that's good for at least one year (two is even better).
