I don't need WiFi, gestures, or speakers (I've a 2 kilowatt sound system capable of just stupid SPL all the way down to 10 Hz). However, I used to look upon 3D as a novelty. Now my feeling is that you haven't lived until you've watched a good movie shot with 3D (stereoscopic) cameras (i.e. not a post conversion to 3D), on a good active shutter 3D TV.
For me, passive 3D, while much improved in the theaters, is still just a novelty - it's ok, but not great. Passive 3D TVs work in a different manner than the passive 3D in theaters, and they're good, too, but not great. Active shutter 3D on a high quality TV, when viewing content that was filmed in 3D (or an animated movie modeled in 3D CGI) is GREAT.
I wasn't looking for 3D as a feature... I just got it because it came with the Sharp model I wanted for other reasons. It was one or two months before I even bothered watching a 3D movie on the TV (no lie) using some PS3 active shutter glasses. I was floored. I will never be without great 3D again.
I think the best 3D I've seen in a movie so far was Monsters, Inc. The 3D was perfect... just absolutely convincing. The TV looked like a giant window into the world of the movie. Of the live action 3D movies I've watched so far, "Hugo" has probably been the best. In the mixed live action/3D CGI category, I'd have to say "Avatar". Sadly, many of my favorite movies that are available in 3D, including "Iron Man 3", "I, Robot", and "Jurassic Park" were not shot in 3D, but post converted (faked), and it's just not nearly as good as the real thing. I found "Jurassic Park" particularly disappointing - it looked so much like a storybook pop-up (2 dimensional characters and structures placed in 3 dimensional space).
Anyway, don't skip 3D in your TV! Also, be especially careful of Samsung these days. They're putting out a lot of units with defects of one sort or another. The average buyer doesn't even notice some of these defects, but if you're paying for a top-of-the-line TV, that's what you should get. Samsung has had a high failure rate in the past couple of years, too. If you can manage to get a Samsung without defects, and that doesn't fail on you within a couple years, they are absolutely awesome. Sony and Sharp are a safer bet, but all of the top manufacturers have been suffering declining quality and higher failure rates, and it killed me when they quit making LCD sets with local dimming (for better contrast) and full array backlighting (for uniform brightness).
